As a conservative, I love reading the answers from the left. Truly amazing (and scary) when it comes to economic questions.
First, let's talk about destroying the economy. Our economy is a free market system, anytime the government usurps the role of the consumer by subsidizing the price or the will of the economic engine (industry) you create a climate in which a product can only exist at the will of the government, not the consumer. And spare me the government is the people, then all you Bush Haters should love eerything he does.
Secondly, for those of you who study business. The issue is not about 'cash cow' but rather, having a product that someone wants and can afford. The free market should dictate whether the product should be there or not. No one would buy BIO-Diesel if it cost $10.00 a gallon. But when 'we the people' pay for $7.00 dollars a gallon from our taxes to buy that product, well then sure it makes all the sense in the world? At that point, private industry is gone and government owns the industry
Lastly, what we can do as Americans. Please start a company and try feeding your family on a product that no one would buy because they can't afford it. No right minded (no pun intended) person would start a venture that would require millions of upfront costs for no chance of every paying of that initial investment. To hide behind the federal government as the agent of industry is a cowards way out, if you wouldn't create a company yourself because you know it would be a financial ruin, then why force an entire nation to pay for something you wouldn't invest in yourself?
