My example is fundamental and fundamentally nothing has changed since the time of Smith and Ricardo.
It's fundamentally absurd. No one would produce furniture for a man who took it and immediately sold it for an impressive markup. The worker would simply manufacture it for himself and sell it.
What a capitalist does is identify a market, pruchase some land, build a factory, purchase tools and equipment, hire numerous people and pay them for weeks and months before a single product is sold. The capitalists invests huge sums before he gets a single dollar for his troubles.
As for Smith and Ricardo, apparently you never heard of the marginal revolution.
You know nothing about the subject of economics that isn't 200 years old.
