“ The demand of buyers, he would say, determines the particular direction of production: it settles whether hats should be made of silk or beaver; whether we should grow corn or spin cotton. But the ultimate force is the capitalist's desire for profit. So long as he can raise labourers' necessaries by employing part of his capital, he can employ the labour as he chooses. He can always produce wealth; all the wealth produced can be exchanged, and the demand always be equal to the supply, since the demand is merely the other side of the supply. ”
