I cite a citation:
Think of the Bill Gates and Steve Jobs, big wealth accumulators in recent times. It wasn’t the magic of compound interest on capital that made them rich; it was intellectual property. They created billions of dollars of business from virtually nothing at all. If you measure the profits as a return on the small amount of initial capital invested, then it looks huge; but capital was no more important an ingredient of the original Apple or Microsoft than cookies or cucumbers.
Capitalism’s nature is not, contrary to Piketty’s claim, to forever protect and augment existing capital. Central to capitalism’s nature is what McCloskey calls “market-tested innovation.” And this innovation inevitably destroys the value of older, less-productive capital that is in competition with with it – in competition with the new capital, the new goods, the new production and consumption processes, and the new knowledge that innovative entrepreneurs create.
