"Free markets" is a very general term. There are all sorts of problems that will emerge. Free markets work best when the transaction between two individuals affects only those individuals. Most often, a transaction between you and me affects a third party. That is the source of all problems for government. That is the source of all pollution problems, of the inequality problem. This reality ensures that the end of history will never come.
Now here's somebody who wants to smoke a marijuana cigarette. If he's caught, he goes to jail. Now is that moral? Is that proper? I think it's absolutely disgraceful that our government, supposed to be our government, should be in the position of converting people who are not harming others into criminals, of destroying their lives, putting them in jail. That's the issue to me. The economic issue comes in only for explaining why it has those effects. But the economic reasons are not the reasons
You could not possibly maintain the current level of government taxation without the taxes being hidden, and they are hidden in two very different ways. They are hidden through withholding, but they are also hidden by being imposed on business, supposedly on business, when really, of course, business can't pay taxes, only people can pay taxes.
The strongest argument for free enterprise is that it prevents anybody from having too much power. Whether that person is a government official, a trade union official, or a business executive. If forces them to put up or shut up. They either have to deliver the goods, produce something that people are willing to pay for, are willing to buy, or else they have to go into a different business.
If the US government spends 40 percent of the nation's income, as it does through either borrowing or taxes, that income is not available for people to spend. The deficit is an indirect method of taxation. Of course, politicians prefer to borrow instead of tax because then someone down the road has to deal with the consequences.
The proper role of government is exactly what John Stuart Mill said in the middle of the nineteenth century in On Liberty. The proper role of government is to prevent other people from harming an individual. Government, he said, never has any right to interfere with an individual for that individual's own good.
I'm not in favor of no government. You do need a government. But by doing so many things that the government has no business doing, it cannot do those things which it alone can do well. There's no other institution in my opinion that can provide us with protection of our life and liberty. However, the government performs that basic function poorly today, precisely because it is devoting too much of its efforts and spending too much of our income on things which are harmful. So I have no doubt that that's the major single problem we face.
If you spend your own money on yourself, you care how much you spend and how well you spend it. If you spend your own money on someone else, you care how much you spend, but you don't care how well it is spent. If you spend someone else's money on yourself, you don't care how much you spend, but you do care how well it is spent. And finally, if you spend someone else's money on someone else, you don't care how much you spend, and you don't care how well it is spent. That is government.
