Actually, you have things completely backwards,
because, the causes of the economic downturns can be traced to government intervention into those economies, and to workers rights and higher demands by those workers for higher salaries and bigger benefits packages. The unions and the people made far too many demands on the corporations, which could no longer support those demands, and so, they either had to downsize or lay off people, or shut down completely, or they stopped investing on growth and fewer people got hired.
It's a fact that, there is a direct relationship between government intervention and the lack of growth of an economy. The more demands that government makes on businesses, the slower the economy will grow, or it will stop growing altogether, and even contract to a size which can't support the work-force. That is precisely what's happened in Europe and it's the same thing happening in the U.S.
The same problems that cause the 1929 depression, are again at play in this economic disaster which is plaguing so much of the world.
But, the disaster is not being caused by businesses or the wealthy.
Economics is, quite clearly, something that you have no understand of whatsoever.
