Capitalism has been the driving mechanism for human society, progress and prosperity in modern history. It is this driving engine that is now about to fail completely.
Capitalism, as in free trade and voluntary interaction, is not going to fail. Much of the establishment of corporatist inefficiency will be in turmoil and the collateral damage for everyone may be severe, but eventually the natural order will recover better and stronger than before.
Yes, without the state, inefficiency will be eliminated. That means, that nearly nothing will be produced, as it was the case within stateless communities in the whole history of mankind. But that wasn't Capitalism. The austrian anarchocapitalists believe, that we will produce even more without the state. That's the greatest economic joke I ever heard.
