People acting in their own self-interest is the fuel for all the discovery, innovation, and prosperity that powers the world.

Politicians and bureaucrats clearly have no idea how complicated markets are. Every day people make countless tradeoffs, in all areas of life, based on subjective value judgements and personal information as they delicately balance their interests, needs and wants. Who is in a better position than they to tailor those choices to best serve their purposes? Yet the politicians believe they can plan the medical market the way you plan a birthday party.

Most people are oblivious to F.A. Hayek's insight that the critical information needed to run an economy - or even 15 percent of one - doesn't exist in any one place where it is accessible to central planners. Instead, it is scattered piecemeal among millions of people. All those people put together are far wiser and better informed than Congress could ever be. Only markets - private property, free exchange and the price system - can put this knowledge at the disposal of entrepreneurs and consumers, ensuring the system will serve the people and not just the political class.

Prosperity comes from leaving people free in a legal system that respects their persons and property so they can pursue their dreams while taking responsibility for their actions.

No transaction happens unless it is voluntary. It only happens if both of you think you win.

The people who have the biggest passion for restricting other people's behavior are the very people we should worry about most. Unfortunately, they keep running for office.

Fraud will always exist. Enforcement of anti-fraud laws is a useful deterrent, but in the end there's no substitute for investor vigilance. Government regulations provide a false sense of security - and that's worth less than no sense of security at all.
