yeah i think appealing to fabrication can be a bit hand-wavy sometimes. like you're saying it's fabricated like how other things are fabricated (since as we all know fabrication happens). but not every fabrication is the same or equally as easy to pull off. to say it was fabricated doesn't say anything about how it was. but that's not even a question that enters ones mind when they think of fabrication. how? well how anything else is fabricated of course..
it can be as much a reaction of disbelief as it is an alternative explanation.
this is from henry george's book progress and poverty. he explains why there is the "enforced idleness" i.e. unemployment. i quite liked this part but i know its a bit dated and i don't really get economics. i think this would be one of those macroeconomic explanations for it.
" [22] All trade, let it be remembered, is the exchange of commodities for commodities, and hence the cessation of demand for some commodities, which marks the depression of trade, is really a cessation in the supply of other commodities. That dealers find their sales declining and manufacturers find orders falling off, while the things which they have to sell, or stand ready to make, are things for which there is yet a widespread desire, simply shows that the supply of other things, which in the course of trade would be given for them, has declined. In common parlance we say that "buyers have no money," or that "money is becoming scarce," but in talking in this way we ignore the fact that money is but the medium of exchange. What the would-be buyers really lack is not money, but commodities which they can turn into money -- what is really becoming scarcer is produce of some sort. The diminution of the effective demand of consumers is therefore but a result of the diminution of production.
[23] This is seen very clearly by storekeepers in a manufacturing town when the mills are shut down and operatives thrown out of work. It is the cessation of production which deprives the operatives of means to make the purchases they desire, and thus leaves the storekeeper with what, in view of the lessened demand, is a superabundant stock, and forces him to discharge some of his clerks and otherwise reduce his demands. And the cessation of demand (I am speaking, of course, of general cases and not of any alteration in relative demand from such causes as change of fashion), which has left the manufacturer with superabundant stock and compelled him to discharge his hands, must arise in the same way. Somewhere, it may be at the other end of the world, a check in production has produced a check in the demand for consumption. That demand is lessened without want being satisfied, shows that production is somewhere checked.
[24] People want the things the manufacturer makes as much as ever, just as the operatives want the things the storekeeper has to sell. But they do not have as much to give for them. Production has somewhere been checked, and this reduction in the supply of some things has shown itself in cessation of demand for others, the check propagating itself through the whole framework of industry and exchange. Now, the industrial pyramid manifestly rests on the land. The primary and fundamental occupations, which create a demand for all others, are evidently those which extract wealth from nature, and, hence, if we trace from one exchange point to another, and from one occupation to another, this check to production, which shows itself in decreased purchasing power, we must ultimately find it in some obstacle which checks labor in expending itself on land. And that obstacle, it is clear, is the speculative advance in rent, or the value of land, which produces the same effects as (in fact, it is) a lockout of labor and capital by landowners. This check to production, beginning at the basis of interlaced industry, propagates itself from exchange point to exchange point, cessation of supply becoming failure of demand, until, so to speak, the whole machine is thrown out of gear, and the spectacle is everywhere presented of labor going to waste while laborers suffer from want.
[25] This strange and unnatural spectacle of large numbers of willing men who cannot find employment is enough to suggest the true cause to whosoever can think consecutively. For, though custom has dulled us to it, it is a strange and unnatural thing that men who wish to labor, in order to satisfy their wants, cannot find the opportunity -- as, since labor is that which produces wealth, the man who seeks to exchange labor for food, clothing, or any other form of wealth, is like one who proposes to give bullion for coin, or wheat for flour. We talk about the supply of labor and the demand for labor, but, evidently, these are only relative terms. The supply of labor is everywhere the same -- two hands always come into the world with one mouth, twenty-one boys to every twenty girls; and the demand for labor must always exist as long as men want things which labor alone can procure. We talk about the "want of work," but, evidently, it is not work that is short while want continues; evidently, the supply of labor cannot be too great, nor the demand for labor too small, when people suffer for the lack of things that labor produces. The real trouble must be that supply is somehow prevented from satisfying demand, that somewhere there is an obstacle which prevents labor from producing the things that laborers want.
[26] Take the case of any one of these vast masses of unemployed men, to whom, though he never heard of Malthus, it today seems that there are too many people in the world. In his own wants, in the needs of his anxious wife, in the demands of his half-cared-for, perhaps even hungry and shivering children, there is demand enough for labor, Heaven knows! In his own willing bands is the supply. Put him on a solitary island, and though cut off from all the enormous advantages which the co-operation, combination, and machinery of a civilized community give to the productive powers of man yet his two hands can fill the mouths and keep warm the backs that depend upon them. Yet where productive power is at its highest development they cannot. Why? Is it not because in the one case he has access to the material and forces of nature, and in the other this access is denied?
[27] Is it not the fact that labor is thus shut off from nature which can alone explain the state of things that compels men to stand idle who would willingly supply their wants by their labor? The proximate cause of enforced idleness with one set of men may be the cessation of demand on the part of other men for the particular things they produce, but trace this cause from point to point, from occupation to occupation, and you will find that enforced idleness in one trade is caused by enforced idleness in another, and that the paralysis which produces dullness in all trades cannot be said to spring from too great a supply of labor or too small a demand for labor, but must proceed from the fact that supply cannot meet demand by producing the things which satisfy want and are the object of labor."
