Political freedom...is a necessary condition for the long-term maintenance of economic freedom.

So long as large sums of money are involved -- and they are bound to be if drugs are illegal -- it is literally impossible to stop the traffic, or even to make a serious reduction in its scope.

We economists don't know much, but we do know how to create a shortage. If you want to create a shortage of tomatoes, for example, just pass a law that retailers can't sell tomatoes for more than two cents per pound. Instantly you'll have a tomato shortage. It's the same with oil or gas.

I think almost every economist would agree that government gets itself in trouble when it tries to interfere with voluntary behavior.

I say thank God for government waste. If government is doing bad things, it's only the waste that prevents the harm from being greater.

Now that I'm 60, every morning I look in the mirror and say, I don't know who you are, stranger, but I'm gonna shave you anyway.

Underlying most arguments against the free market is a lack of belief in freedom itself.

Germany cannot get out of the euro. What it has to do, therefore, is make the economy more flexible -- to eliminate the restrictions on prices, on wages and on employment; in short, the regulations that keep 10 percent of the German workforce unemployed.

Well first of all, tell me, is there some society you know of that doesn't run on greed? You think Russia doesn't run on greed? You think China doesn't run on greed? What is greed?

How did we make the transition from using wood to using coal, from using coal to using oil, from using oil to using natural gas? How in God's name did we make that transition without a Federal Energy Agency?

The most unresolved problem of the day is precisely the problem that concerned the founders of this nation: how to limit the scope and power of government. Tyranny, restrictions on human freedom, come primarily from governmental restrictions that we ourselves have set up.

The Internet moves us closer to perfect information on markets. Individuals and companies alike can buy and sell across borders and jurisdictions wherever they find the best match of supply and demand.

We do not influence the course of events by persuading people that we are right when we make what they regard as radical proposals. Rather, we exert influence by keeping options available when something has to be done at a time of crisis.

If a tax cut increases government revenues, you haven't cut taxes enough.

The existence of a free market does not of course eliminate the need for government. On the contrary, government is essential both as a forum for determining the rule of the game and as an umpire to interpret and enforce the rules decided on.

My major problem with the world is a problem of scarcity in the midst of plenty ... of people starving while there are unused resources ... people having skills which are not being used.

The argument for the free market is a complicated and sophisticated one and depends on demonstration of secondary effects. I have confidence market efficiency will win out.

Rich people are the experimental ground for every new development. The nature of progress is that what begins as a luxury for the rich becomes a necessity for the poor as it's developed and passed on.

Many people want the government to protect the consumer. A much more urgent problem is to protect the consumer from the government.

On aging societies, there is no reason why a country that has a lot of old people can't be prosperous if, during their working lives, individuals provide for their retirement.
