Talk of stimulus has revived the work of John Maynard Keynes, a 20th-century British economist who urged government spending to fight recession. A century earlier, French economist Frédéric Bastiat gave a different view. Here are excerpts from Keynes's "The General Theory of Employment, Interest, and Money" and Bastiat's, "What is seen, and what is not seen."
John Maynard Keynes on the need for government action
The outstanding faults of the economic society in which we live are its failure to provide for full employment and its arbitrary and inequitable distribution of wealth and incomes.
At the same time we must recognize that only experience can show how far the common will, embodied in the policy of the State, ought to be directed to increasing and supplementing the inducement to invest; and how far it is safe to stimulate the average propensity to consume, without forgoing our aim of depriving capital of its scarcity-value within one or two generations. It may turn out that the propensity to consume will be so easily strengthened by the effects of a falling rate of interest, that full employment can be reached with a rate of accumulation little greater than at present. In this event a scheme for the higher taxation of large incomes and inheritances might be open to the objection that it would lead to full employment with a rate of accumulation which was reduced considerably below the current level....
In some other respects the forgoing theory is moderately conservative in its implications. For whilst it indicates the vital importance of establishing certain central controls in matters which are now left in the main to individual initiative, there are wide fields of activity which are unaffected. The State will have to exercise a guiding influence on the propensity to consume partly through its scheme of taxation, partly by fixing the rate of interest, and partly, perhaps, in other ways. Furthermore, it seems unlikely that the influence of banking policy on the rate of interest will be sufficient by itself to determine an optimum rate of investment. I conceive, therefore, that a somewhat comprehensive socialization of investment will prove the only means of securing an approximation to full employment; though this need not exclude all manner of compromises and of devices by which public authority will co-operate with private initiative. But beyond this no obvious case is made out for a system of State Socialism which would embrace most of the economic life of the community. It is not the ownership of the instruments of production which it is important for the State to assume. If the State is able to determine the aggregate amount of resources devoted to augmenting the instruments and the basic rate of reward to those who own them, it will have accomplished all that is necessary....
Our criticism of the accepted classical theory of economics has consisted not so much in finding logical flaws in its analysis as in pointing out that its tacit assumptions are seldom or never satisfied, with the result that it cannot solve the economic problems of the actual world.… [A]part from the necessity of central controls to bring about an adjustment between the propensity to consume and the inducement to invest, there is no more reason to socialise economic life than there was before....
The central controls necessary to ensure full employment will, of course, involve a large extension of the traditional functions of government....
[A]bove all, individualism, if it can be purged of its defects and its abuses, is the best safeguard of personal liberty in the sense that, compared with any other system, it greatly widens the field for the exercise of personal choice. It is also the best safeguard of the variety of life….
Whilst, therefore, the enlargement of the functions of government, involved in the task of adjusting to one another the propensity to consume and the inducement to invest, would seem to a nineteenth-century publicist or to a contemporary American financier to be a terrific encroachment on individualism, I defend it, on the contrary, both as the only practicable means of avoiding the destruction of existing economic forms in their entirety and as the condition of the successful functioning of individual initiative...
The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist.… [S]oon or late, it is ideas, not vested interests, which are dangerous for good or evil.
Frédéric Bastiat on the folly, and unseen effects, of stimulus
Have you ever witnessed the anger of the good shopkeeper, John Q. Citizen, when his careless son happened to break a square of glass?…
Suppose it cost six francs to repair the damage, and you say that the accident brings six francs to the glazier's trade – that it encourages that trade to the amount of six francs – I grant it ... you reason justly. The glazier comes, performs his task, receives his six francs, rubs his hands, and, in his heart, blesses the careless child. All this is that which is seen.
But if, on the other hand, you come to the conclusion, as is too often the case, that it is a good thing to break windows, that it causes money to circulate, and that the encouragement of industry in general will be the result of it, you will oblige me to call out, "Stop there! your theory is confined to that which is seen; it takes no account of that which is not seen."
It is not seen that as our shopkeeper has spent six francs upon one thing, he cannot spend them upon another. It is not seen that if he had not had a window to replace, he would, perhaps, have replaced his old shoes, or added another book to his library. In short, he would have employed his six francs in some way, which this accident has prevented.
Let us take a view of industry in general, as affected by this circumstance. The window being broken, the glazier's trade is encouraged to the amount of six francs; this is that which is seen. If the window had not been broken, the shoemaker's trade (or some other) would have been encouraged to the amount of six francs; this is that which is not seen.
And if that which is not seen is taken into consideration, …it will be understood that neither industry in general, nor the sum total of national labor, is affected, whether windows are broken or not.
Now let us consider John Q. Citizen himself.
In the former supposition, that of the window being broken, he spends six francs, and has neither more nor less than he had before, the enjoyment of a window.
In the second, where we suppose the window not to have been broken, he would have spent six francs on shoes, and would have had at the same time the enjoyment of a pair of shoes and of a window.
Now, as John Q. Citizen forms a part of society, we must come to the conclusion, that, taking it altogether, and making an estimate of its enjoyments and its labors, it has lost the value of the broken window.
When we arrive at this unexpected conclusion: "Society loses the value of things which are uselessly destroyed;" and we must assent to a maxim which will make the hair of protectionists stand on end – To break, to spoil, to waste, is not to encourage national labour; or, more briefly, "destruction is not profit."
What will you say, Moniteur Industriel? What will you say, disciples of good M. F. Chamans, who has calculated with so much precision how much trade would gain by the burning of Paris, from the number of houses it would be necessary to rebuild?
I am sorry to disturb these ingenious calculations ... but I beg him to begin them again, by taking into the account that which is not seen, and placing it alongside of that which is seen. The reader must take care to remember that there are not two persons only, but three concerned in the little scene which I have submitted to his attention. One of them, John Q. Citizen, represents the consumer, reduced, by an act of destruction, to one enjoyment instead of two. Another under the title of the glazier, shows us the producer, whose trade is encouraged by the accident. The third is the shoemaker (or some other tradesman), whose labour suffers proportionably by the same cause. It is this third person who is always kept in the shade, and who, personating that which is not seen, is a necessary element of the problem. It is he who shows us how absurd it is to think we see a profit in an act of destruction. It is he who will soon teach us that it is not less absurd to see a profit in a restriction, which is, after all, nothing else than a partial destruction. Therefore, if you will only go to the root of all the arguments which are adduced in its favour, all you will find will be the paraphrase of this vulgar saying, "What would become of the glaziers, if nobody ever broke windows?"
