Law for Our Time</strong></font>
</div>
<font size="4">by Sean Corrigan</font>
<font size="2">[Posted September 5. 2002]</font>
<font size="2">[img][/img] How
many times have you heard the unthinking comment that we need to keep
consumption burning brightly because"consumption is two-thirds of GDP"?</font>
<font size="2">There it is, after all, in black and white. If you look up
the GDP release, you see that, in 2001, nominal GDP was $10 trillion dollars
and change, while personal consumption expenditures were a touch under $7
trillion. QED.</font>
<font size="2">Fair enough, but be aware that this is very much a circular
argument which presupposes that this GDP measure can provide an accurate
reflection of the process of wealth generation in the first place (when in
fact it is rooted in J.M. Keynes's facile identity that <em>Income =
Consumption plus Investment, +/- Net External Trade and Government</em>).</font>
<font size="2">So, let us assume that what makes us rich is not consumption.
Consumption is merely that fraction of our income and assets that we decide to
exhaust today in pursuits other than those which will either add to the
possibilities of greater output in future, or act as a prudential fund
against unforeseen needs.</font>
<font size="2">Clearly, it is production that matters, for this is what
ultimately lifts us out of savagery. That this should be controversial shows
how far we have fallen from the good common sense of our forefathers.</font>
<font size="2">For we can play Oliver Twist all we like, importunately
holding up our plates for more, but unless we offer something in return, we
are unlikely to be able to rely on our portion being replenished at will.</font>
<font size="2">This simple insight was encapsulated by the classical
economist Jean-Baptiste Say, who expressed this to the effect that Supply
creates its own Demand. Or, to put it in colloquial English,"You want
some of these here beans? What you got in yer wagon to trade fer 'em?"</font>
<font size="2">For the best part of the century that witnessed the
flowering of Manchester liberalism, Say's aphorism came to be taken for
granted, as a truism. Namely, it was accepted that if you worked to produce a
saleable good (or to offer a saleable service), you were then entitled to
exchange it for the fruits of someone else's efforts at a price to be freely
negotiated between the two of you.</font>
<font size="2">Should the wants of vendor and purchaser not coincide
exactly, or should the two be separated by even the width of an ocean, this
was no problem, so long as men felt they could rely upon tokens of exchange
that equitably reflected the work which went into their generation--that is,
upon an honest money to use as a medium of this indirect exchange. </font>
<font size="2">Sadly, the idea of resorting to work and entrepreneurialism,
as a means to material well-being, has historically become a poor second to
the idea of acquiring resources through theft. This robbery is always most
effectively perpetrated when disguised and when legally underwritten by the
threat of political violence--i.e., when it is committed by the State.</font>
<font size="2">This comes about because theft is a much less arduous task
than the capitalist process of striving best to serve the capricious tastes
and fluctuating relative valuations of consumers in open competition with
one's fellow entrepreneurs. It is also a much more glamorous occupation and is
more likely to grant one a fabled posterity: few children are read tales of
successful grocers and haberdashers at bedtime, preferring to hear of the
heroic thefts of conquerors, warriors, and presidents instead.</font>
<font size="2">Thus, what John Berger aptly defined in his book, <em>The
Sinews of Power</em>, as the"fiscal-military state," or what the
Austrians less charitably decry as the"warfare-welfare state,"
invariably sees those at the pinnacle of political-military power, disrupting
this benign process by siphoning off a tribute every time goods pass over the
shop counter. In this they are usually abetted--if not actually
manipulated--by those who control the purse strings.</font>
<font size="2">They used to exact this levy by sheer brigandage and the
overt threat of physical force; now, the means are more subtle and tend to
involve the hidden redistribution of resources through the Unholy Trinity of
Debt, Taxes, and Paper Money.</font>
<font size="2">Now, one of the sad facts of such impositions is that they
always lead to undue hardship. The entrepreneurial bourgeois and the diligent
artisan alike have to carry to market not just goods for their own utility,
but also goods sufficient to support a posse of bureaucrats, court lackeys,
armoured hooligans, tax gatherers, assessors, monopolists, subsidy-mongers,
and welfare dispensers, as well as the power elite and their financiers
themselves.</font>
<font size="2">If this parasitism is sufficiently subtly interwoven in the
social fabric--as nearly a century of fiat money and creeping collectivism has
largely accomplished today--the impoverished and bewildered creators of wealth
cry out for help in their anguish and foolishly come to mistake the shaggy
pelts of the state wolfpack for the robes of a gentle shepherd whom they trust
will tenderly deliver them from their miseries.</font>
<font size="2">Thus, government frustration of the market process
inexorably leads to the call for the government to Do Something once again to
counteract its own malfeasance. As an astute 18th-century Briton succinctly
put it,"Armies beget taxes, taxes beget unrest, unrest begets armies."</font>
<font size="2">In this way, the fourth decade of this century--after a long
period of false and frenzied prosperity that was fueled like today,
largely by debt--witnessed a crisis, caused not by the breakdown of free
market capitalism, as the state's apologists have maintained ever since.
Rather, the Great Depression was caused by the febrile convulsions made
inevitable by the suppression of the market's workings throughout a decade of
monetary deceit and a consequently unsupportable credit expansion. This was
worsened by the willful frustration of the international division of labor
through high tariffs, and by the unwillingness to settle the entwined issues
of inflationary war debt and punitive reparations in a timely and realistic
manner.</font>
<font size="2">In the midst of this turmoil of the depression, the
ever-opportunistic and dangerously meretricious Keynes stepped forward,
seeking to persuade people that Say had it all back to front: that, in fact,
it was Demand that created its own Supply ("Please, sir, may I have some
more?") and that all we needed was to give people extra monetary tokens,
unbacked by anything tangible, for the prodigals to restore us to prosperity
simply through spending them.</font>
<font size="2">But if we reckon that being bribed to set fire to an
overplanted forest is likely to add less value than would setting a new
clearing price for any surfeit of lumber, or exploring to what other exciting
new productive uses we can put the wood, let us go back to this question of
production, to see why Keynes and all his Myrmidons are wrong.</font>
<font size="2">We need to visualize the critical concept of the structure
of production, the idea that what we are dealing with is not a crude
hydrological exercise in plumbing, as actually physically embodied by Keynes's
acolyte, Phillips, of"curve" fame. Instead, we must return to F.A.
Hayek's useful motif of the economy as a right-angle triangle, with elapsed
time along the bottom, and some measure of output, or revenues, going up the
page.</font>
<font size="2">Raw materials and capital goods are way up there at the apex,
far distant in time from their final realization as consumers' goods.
Consumption itself represents a slice along the nearby vertex, and"fixed
investment," as arbitrarily defined in the GDP numbers, is merely a
sliver along the hypotenuse.</font>
<font size="2">There are multiple steps and innumerable interconnections in
this structure, a structure which is, in fact, not so much a simple triangle
as it is a multi-dimensional manifold, knotted with loops, feedbacks, and
bifurcations.</font>
<font size="2">Meshed in all this complexity, we must never lose sight of
the fact that the passage of time is an immutable constraint, and also that
since most activities take place at times remote from their fruition in
consumption, savings are an essential element for the support of such deferred
consummation.</font>
<font size="2">As an aside, to know how much time one has to complete a
process, one must know what savings are available for the sustenance of its
factors. The means by which both are signaled is the natural rate of interest.
That is why any interference with this regulatory influence by the action of
the central bank is so prejudicial to prosperity.</font>
<font size="2">Returning to our theme, we should begin to see that GDP can
only give us a very partial (in both senses!) insight into the mechanisms at
work.</font>
<font size="2">Keynes effectively wants us to believe we can truly
appreciate the artistic achievements, the engineering prowess, and the
religious sensibilities of the Egyptian builders by taking the Great Pyramid
of Cheops and weighing the first course of blocks at the base, then adding in
some reckoning of the amount of whitewash limning the rest of the masonry.</font>
<font size="2">So, for a fairer picture--though still only a crude sketch
of the whole intricate mechanism at work--consider the BEA's Input-Output data
instead. For 1998, when these were last compiled, nominal GDP stood at $8.8
trillion, and personal consumption was $5.9 trillion. Manufacturing seemed to
be fairly inconsequential at $1.5 trillion in the GDP numbers ("Nobody
cares about manufacturing anymore!") and made a smaller contribution than
either finance ($1.7 trillion) or services ($2.1 trillion).</font>
<font size="2">But now look at what was actually being made and sweated
over within the economy, providing jobs, on the one hand, and the opportunity
of profits on the other. Let us sneak a glimpse at the division of labor in
all its glory.</font>
<font size="2">The total gross output of the economy now comes to $15.4
trillion in turnover, and manufacturing--at $3.9 trillion--suddenly swells to
being the largest constituent of them all, 55 percent greater than finance,
and 10 percent larger even than the much-vaunted service sector.</font>
<font size="2">Manufacturing emphatically does matter, for it now becomes
responsible for fully a quarter of all productive activity and--here is the
crucial point--60 percent of that provides an input for other
intermediate industries, and 60 percent of that fraction, in turn, goes back
into the other stages of manufacturing itself, with only 25 percent destined
straight for consumption and a lowly 15 percent to the GDP-defined"fixed-investment"
category.</font>
<font size="2">Armed with this fresh perspective, now ask yourself whether
you are ready to continue to accept blindly that we are living in a"service
economy," or that all will be well"as long as the consumer keeps
spending" (rather than if the worker--and the manufacturing worker, at
that--keeps usefully producing), or that businesses merely have an"inventory
problem" (not a fixed-capital problem) to overcome.</font>
<font size="2">But, under the Keynes version--espoused uncritically by
central banks, Wall Street"analysts," and politicians
everywhere--if business falters, do not be alarmed! We can simply send people
to the shops waving their new Federal Reserve purchasing coupons, and urge
them to be profligate.</font>
<font size="2">Manufacturing, for so long misled by the total distortion of
the prices of capital, inputs, and final sales, will then automatically
reorient itself to satisfy these demands--despite the fact that it was
patently unable to do this sustainably, much less profitably, before the
masses were given their extra vouchers.</font>
<font size="2">We are told, by the Inflationists, that currently there is
overproduction and that prices are falling. If we do not take care,
consumption will falter unless we induce the Fed to prop up demand by
expanding the supply of money.</font>
<font size="2">Granted, there is specific overproduction perhaps--the
distortions of the credit expansion have ensured that, thank you, Sir Alan--so
there may be a surfeit of automobiles and disk drives and broadband capacity,
among many others. But do we really have everything else we want for the
asking?</font>
<font size="2">Do we have the best shoes, the finest clothes, limitless
energy with no harmful waste products, instant medical treatment, the highest
standards of education for our children, delay-free means of transport--in
fact, all the delights of an earthly Paradise?</font>
<font size="2">Of course not.</font>
<font size="2">You must therefore be able to appreciate that consumption is
highly unlikely to fail through any sudden fulfillment of the consumers'
endless shopping list--barring a miraculous outbreak of religious hysteria, a
global conversion to asceticism.</font>
<font size="2">What instead may fail--indeed, has been failing--is these
would-be consumers' ability to comply with Say's Law.</font>
<font size="2">They are unable to find an outlet for their particular
skills and talents because the matrix of relative (never absolute, much less
average) prices has been made replete with harmful rigidities--thanks to the
Fed and the rest of the government --and so cannot adjust to offer them a
niche.</font>
<font size="2">Moreover, such niches as do exist are harder to exploit to
their maximum because so much scarce capital has been wasted or misallocated,
giving people fewer tools with which to work.</font>
<font size="2">This, in turn, means these unfortunates cannot buy all they
want, except by taking up yet more debt, and this only perpetuates those
faulty entries in that all-important matrix of relative prices. It also
progressively alienates their future incomes, and thus comes to jeopardize the
soundness of their increasingly foolhardy, morally hazardous lenders.</font>
<font size="2">Put differently, supply creates its own demand, except where
unsaved credit intrudes, and that can only prolong the agony, not cure the
misalignment</font>
<font size="2">But this is all very well in theory. Surely, there must be
too much production. For why else do we constantly hear the lament on
everyone's lips that"Businesses have no Pricing Power!"--a wail
which usually precedes a call for more Fed funny money to combat this malaise?</font>
<font size="2">It is a pivotal fact that this misses the larger truth:
businesses NEVER have control over prices--not on a free market. Rather, what
has been removed from them today is some measure of influence over their costs.</font>
<font size="2">This has come about because the vast effusion of unsaved
credit is propping up demand from those who supply nothing in return, except
their credit cards and their home equity cash-outs.</font>
<font size="2">If all these nonsuppliers were instead left to price
themselves back into productive work before they bought things, and if the
goods they could no longer honestly afford in the interim were allowed to fall
in price to reflect this fact, more businesses might then be able to take up
what would now be both cheaper labor and cheaper resources. They would be
induced to do this because this relative repricing would help furnish them
with a greater faith that their hopes of making a genuine return on capital
were not in vain.</font>
<font size="2">This they could also do, since they would have more
assurance of successfully supplying a mix of goods and services that was more
nearly in tune with the expression of only those wants which had justifiably
earned their gratification in the demander's own concurrent contribution to
output. That way, the economic organism would be likely to rediscover its
holistic, dynamic balance between the yin and yang of production and
consumption, and investment and saving.</font>
<font size="2">That way, only those who Supply could Demand in their turn.</font>
<font size="2">Extra fiat money can do little to substitute for this
necessary immune response, or to speed this time-consuming recuperative
process. It cannot give the outfoxed chessmaster two moves to his opponent's
one to avoid a mate, nor can it teach infantrymen instantly to ride cavalry
chargers to repel the foe.</font>
<font size="2">It cannot create wealth, for wealth is only minimally
coincident with today's mockery of money.</font>
<font size="2">It can, however, arbitrarily transfer ownership of what
wealth still exists. It can lock sub-par businesses in place and suck their
creditors deeper into the mire alongside them. It can thus foster an unwelcome
competition for resources which elevates their costs beyond the reach of truly
productive businesses. It can choke the Garden with the weeds of those
undertakings which are only able to flourish under these highly artificial
conditions--the housing boom springs to mind today.</font>
<font size="2">Unfortunately for the legions of Inflationists (Californian
Money Managers, or otherwise!), there are no shortcuts to betterment, but
there are all too many diversions, distractions, and dead ends, and the most
misleading road map in the world is the one printed at 20th Street and
Constitution Avenue in Washington, deep inside the Marriner S. Eccles building.</font>
