There is not a line in 'The Wealth of Nations' that is not still applicable to this day.

The only relevant test of the validity of a hypothesis is comparison of prediction with experience.

I'm in favor of legalizing drugs. According to my values system, if people want to kill themselves, they have every right to do so. Most of the harm that comes from drugs is because they are illegal.

The future of private enterprise capitalism is also the future of a free society. There is no possibility of having a politically free society unless the major part of its economic resources are operated under a capitalistic private enterprise system.

The Internet is the most effective instrument we have for globalization.

That's an interesting paradox to think about. Make it legal and it's no good. Why? Because as long as it's illegal the people who come in do not qualify for welfare, they don't qualify for social security, they don't qualify for the other myriad of benefits that we pour out from our left pocket to our right pocket. So long as they don't qualify they migrate to jobs. They take jobs that most residents of this country are unwilling to take. They provide employers with the kind of workers that they cannot get. They're hard workers, they're good workers, and they are clearly better off.

I think that the Internet is going to be one of the major forces for reducing the role of government.
