Sheldon Richman discusses libertarianism and capitalism.
"What looks to the unschooled like exploitation, is not exploitation at all. The workers and landowner must have found the exchange worthwhile or they would not have agreed to it. If the capitalist’s vision of the future is wrong and consumers don’t like the final product or the asking price, the capitalist is out of luck. He suffers losses. He can’t get a refund from the workers and landowners."
Eugen Bohm-Bawerk:
The completely just proposition that the worker is to receive the entire value of his product can be reasonably interpreted to mean either that he is to receive the full present value of his product now or that he is to get the entire future value in the future. But … the socialists interpret it to mean that the worker is to receive the entire future value of his product now.
Rothbard:
Very good.
Another aspect of this that I didn't see mentioned is the work of identifying the opportunity. The worker may be the one making the product, but the worker may not even have known there was a demand for said product, or who the buyers are. Finding that stuff out takes time too.
Yes. Discovery of profit opportunities is something Israel Kirzner focused on. I haven't read as much of his work, but what I have read is interesting.
