You're asserting this based on religious beliefs; you've read and heard this statement a lot in the popular media, and it's part of the Republican catechism. But it's false. In fact, the truth is quite the opposite - a heavily regulated environment is the BEST for business, the economy, and productivity. The United States is a good place for business precisely because it is heavily regulated. Nobody steals your plant equipment because there are lots of cops and Marines. People pay their end of the contract because there are lots of courts. Banks don't steal your deposits because the bank regulators are strong, well, that one may be inoperative in 2012 but it used to be true.
The closer the United States comes to non-regulated countries like Somalia, the closer its economy will be to Somalia's.
There's also tendency toward convenient over-simplification that's common among we nerds. It's a valuable tool; classical mechanics is a lot easier to learn and reason about if you ignore things like air resistance. One of the most important skills for a software developer is willfully ignoring 99% of the complexity to extract the 1% it's worth teaching the computer about.
But it's also dangerous. The simplifying assumptions of economics are things like perfect information, perfect rationality, unlimited mental processing power, unyielding will, and entirely unbiased cognition. That's useful in theory, but misleading in practice. Misleading twice over, because that's how people would like to see themselves. "I don't need regulation! I'm too smart to ever be fooled!"
