The Money-Making Machine Revealed — Das Kapital

Marx turns from circulation in general to capital in particular. Merchants and usurers already live by buying in order to sell, but the modern form is more restless: money enters circulation not to acquire use-values for consumption, but to return expanded as M-C-M'. This movement cannot be explained by simple trickery inside one fair exchange.

The capitalist must find commodities whose consumption creates more value than they cost, and he must keep the process repeating. Use-values matter only as bearers of exchange-value. The aim is not the commodity but the augmentation of money itself, a never-ending chase that reshapes production around profit.

The chapter ends by insisting that capital is a social relation in motion. It appears as a pile of money or machinery, yet its essence is the compulsive return to circulation with a surplus. Marx has named the formula. The next task is to prove where the surplus can legally come from.
