If you doubt it, then I would suggest picking up a Wall Street Journal and look at what the people that make decisions in business say. Don't take my word for it. Get it directly from the horse's mouth.
The free market can take a serious hit when you have an event like a 9/11 (hence the purpose of the strike). However, outside of that, if government can get out of the way (save for preventing monopolies and enforcing laws against fraud) free enterprise will fare tremendously better. People as consumers can then pick the winners and losers rather than a few bureaucrats in DC that think they know what's best for the entire country (and in some cases, the world).
George Bush started something absolutely horrible at the end of his presidency with TARP and his stimulus bills. I understand the reasoning that we needed to keep the debt solvent for foreign investment, but the current administration has taken the concept and passed out free candy ever since. Never mind that our kids will have to shoulder the burden of paying the debt (likely through runaway inflation... or as Bernanke calls it, "Quantitative Easement") that we racked up. "Great work son! Here's my credit card bill. Good luck with that!"
Something that escapes this generation of Americans is the discipline of failure. If you aren't allowed to fail at the expense of your peers, then you have no reason to fix what's broken. Meanwhile, everyone else has to shoulder your continual fugups because the bureaucrats decided that they're too important to endure managed bankruptcy like everyone else.
Look, I agree that a free market governed through effective regulations is the best way to run an economy. But you cant claim that all government involvement hurts the economy.
For instance China's government is very intertwined with the market, yet they have experienced massive economic growth over the last 20 years. Not saying I want to become China, but it is okay to look around and imitate the successes of other nations even if they dont happen to love freedom as much as we do
