Hey, don't forget about abolishing anti-trust laws. If you really want to go no holds barred, that's a must. The ultimate end of unregulated competition would be to have a monopoly over a given industry, or maybe multiple industries. Once you've eliminated your competitors, there's no sense in letting new upstarts try to enter the market.
Seriously though, I think there needs to be some regulation without going to the extreme of oppressive regulation. I just don't know how to do it. If I did, I'd probably run for Congress. I think what we need to introduce into business (somehow) is honesty and full disclosure. For example, if you're an investment banker and you're selling mortgage-backed securities, and you have to tell your customers, "Hey, we bought these mortgages from banks that were giving out loans like Halloween candy. They didn't check credit ratings or verify the income of the borrowers or anything!" You wouldn't sell a single security. So if you had to be honest, you would make sure that you only bought mortgages from banks who only loaned money to people who were good credit risks, and surprise! the whole banking collapse and subsequent bailout could have been averted. Likewise, if you had to tell people that the reason your soccer balls are so cheap is because the twelve-year-olds who sew them get a beating when they fall behind quota or ask for a raise, you would find that most people would pay a little bit more for a soccer ball made by an adult for a meager wage, but one that they agreed to and would not be beaten for complaining about.
I don't know how we get that kind of honesty and full disclosure in the business world, but that's what we need. Just ask the owners of "clean diesel" products made by Volkswagen.
