And, first, I premise that labour is, as I have already intimated, a commodity, and as such, an article of trade. If I am right in this notion, then labour must be subject to all the laws and principles of trade, and not to regulations foreign to them, and that may be totally inconsistent with those principles and those laws. When any commodity is carried to market, it is not the necessity of the vender, but the necessity of the purchaser that raises the price. The extreme want of the seller has rather (by the nature of things with which we shall in vain contend) the direct contrary operation. If the goods at market are beyond the demand, they fall in their value; if below it, they rise. The impossibility of the subsistence of a man, who carries his labour to a market, is totally beside the question in this way of viewing it. The only question is, what is it worth to the buyer? But if authority comes in and forces the buyer to a price, who is this in the case (say) of a farmer, who buys the labour of ten or twelve labouring men, and three or four handycrafts, what is it, but to make an arbitrary division of his property among them?

The key to understanding the situation is the most elementary principle of economics: the law of demand — the higher the price of anything, the less of it people will be willing to buy. Make labor of any kind more expensive and the number of jobs of that kind will be fewer. Make carpenters more expensive, and fewer houses than otherwise will be built, and those houses that are built will tend to use materials and methods requiring less carpentry. Raise the wage of airline pilots, and air travel will become more expensive. Fewer people will fly, and there will be fewer jobs for airline pilots. Alternatively, reduce the number of carpenters or pilots, and they will command higher wages. Keep down the number of physicians, and they will be able to charge higher fees.

In my considered opinion, salary is payment for goods delivered and it must conform to the law of supply and demand. If, therefore, the fixed salary is a violation of this law - as, for instance, when I see two engineers leaving college together and both equally well trained and efficient, and one getting forty thousand while the other only earns two thousand , or when lawyers and hussars, possessing no special qualifications, are appointed directors of banks with huge salaries - I can only conclude that their salaries are not fixed according to the law of supply and demand but simply by personal influence. And this is an abuse important in itself and having a deleterious effect on government service.

What exclusively determines the magnitude of the value of any article is therefore the amount of labour socially necessary, or the labour-time socially necessary for its production.

In an exchange economy everybody’s money income is somebody else’s cost. Every increase in hourly wages, unless or until compensated by an equal increase in hourly productivity, is an increase in costs of production. An increase in costs of production, where the government controls prices and forbids any price increase, takes the profit from marginal producers, forces them out of business, means a shrinkage in production and a growth in unemployment. Even where a price increase is possible, the higher price discourages buyers, shrinks the market, and also leads to unemployment. If a 30 percent increase in hourly wages all around the circle forces a 30 percent increase in prices, labor can buy no more of the product than it could at the beginning; and the merry-go-round must start all over again.

The balance between consumption and production makes price. The market settles, and alone can settle, that price. Market is the meeting and conference of the consumer and producer, when they mutually discover each other’s wants. Nobody, I believe, has observed with any reflection what market is, without being astonished at the truth, the correctness, the celerity, the general equity, with which the balance of wants is settled. They who wish the destruction of that balance, and would fain by arbitrary regulation decree, that defective production should not be compensated by encreased price, directly lay their axe to the root of production itself.

It is, perhaps, impossible to proportion exactly the price of labor to the profits it produces; and it will also be said, as an apology for the injustice, that were a workman to receive an increase of wages daily he would not save it against old age, nor be much better for it in the interim.

Where there is scarcity, price is no object. This basic tenet of supply and demand would later become a governing principle of my investment philosophy.

One of the most expensive commodities a nation can have is a cheap labor force. From this a host of consequences leaped forth as inevitable. — If you get labor for almost nothing, you have no incentive to buy expensive tools and the quality of your product will lag behind that of nations who do use the best tools on the market. — If you keep your labor occupied on menial tasks that are best suited to machines, your work force never develops those skills that would earn you more income. — If you employ ten to do the work of one, none of the ten will work to maximum efficiency because each will realize that what he or she does isn’t significant. — If you don’t pay your labor good wages, how can they ever afford to buy what you make? You limit your potential market by 50 percent at least, and if every employer in the region pays the same low wages, your market can vanish altogether. — A nation’s wealth is generated when the money from wages is quickly spread around because this causes more goods to be produced, and real wealth consists in the making and interchange of goods.
And then I made the discovery: ‘Ricardo was wrong. There is no fixed quantum of money in the world, or in any nation. The rich man doesn’t suffer deprivation when labor gets a bigger share, for that larger amount means a bigger total for him.’” — Chapter VII, “Ideas”, page 257-258

God sells us all things at the price of labor.

Fundamentally, all marketing exists to influence the supply and demand curve.

Value is not determined by those who set the price. Value is determined by those who choose to pay it.

People always get what they want. But there is a price for everything. Failures are either those who do not know what they want or are not prepared to pay the price asked them. The price varies from individual to individual. Some get things at bargain-sale prices, others only at famine prices. But it is no use grumbling. Whatever price you are asked, you must pay.

These labourers, who must sell themselves piece-meal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.
