A viable economy is built upon the truth of producer supply vs. consumer demand. When the government essentially "subsidizes" a market, it creates a false market grounded in decieving the market by creating scenarios that would not otherwise exist.
There is supposed to be some Darwinism regarding a free market. The bad ideas/businesses die, or are defeated by the better ideas/buisnesses. Government interfering and propping up failing industries, delays or prohibits true stimulus, which comes from the root truths of the basics of supply/demand economics.
