Imagine for a moment that there is a foreign government that receives billions of dollars a year in “aid” and other benefits from the United States taxpayer. Consider beyond that, the possibility that that government might take part of the money it receives and secretly recycle it to groups of American citizens in the United States that exist to maintain and increase that money flow while also otherwise serving other interests of the recipient country. That would mean that the United States is itself subsidizing the lobbies and groups that are inevitably working against its own interests.

It is a basic fact of economic life in capitalist economies: recessions happen, there are cycles of boom and bust.
By the 1850s, Karl Marx had pretty well figured out the how and why, the underlying mechanisms. His account has held up well over the years, though you would hardly know it to hear mainstream macro-economists tell it.
