In his Communist Manifesto, published in 1848, Karl Marx proposed 10 measures to be implemented after the proletariat takes power, with the aim of centralizing all instruments of production in the hands of the state. Proposal Number Five was to bring about the “centralization of credit in the banks of the state, by means of a national bank with state capital and an exclusive monopoly.”
If he were to rise from the dead today, Marx might be delighted to discover that most economists and financial commentators, including many who claim to favour the free market, agree with him.
The author goes on to point out that only the Austrian School of economics realistically opines that the boom cannot go on forever. Interestingly, I have been reading a history and analysis of the Great Depression by Murray N. Rothbard, called America's Great Depression. You can download a PDF copy of the book from the Mises Institute (which embraces the Austrian School of economics) here. Rothbard was (and may still be) with the Mises Institute. The essential premise of the book is that there will always be a boom and bust cycle in the economy and that government intervention can lengthen the boom cycle, but when the bust cycle comes around it will be much worse. That is what we saw with the Great Depression and it looks like that may be what is happening now.
