A front-page headline in the New York Times captures much of the economic confusion of our time: "Fewer Options Open to Pay for Costs of College."
The whole article is about the increased costs of college, the difficulties parents have in paying those costs, and the difficulties that both students and parents have in trying to borrow the money needed when their current incomes will not cover college costs.
All that is fine for a purely "human interest" story. But making economic policies on the basis of human interest stories -- which is what politicians increasingly do, especially in election years -- has a big down side for those people who do not happen to be in the categories chosen to write human interest stories about.
The general thrust of human interest stories about people with economic problems, whether they are college students or people faced with mortgage foreclosures, is that the government ought to come to their rescue, presumably because the government has so much money and these individuals have so little.
Like most "deep pockets," however, the government's deep pockets come from vast numbers of people with much shallower pockets. In many cases, the average taxpayer has lower income than the people on whom the government lavishes its financial favors.
Costs are not just things for government to help people to pay. Costs are telling us something that is dangerous to ignore.
The inadequacy of resources to produce everything that everyone wants is the fundamental fact of life in every economy -- capitalist, socialist or feudal. This means that the real cost of anything consists of all the other things that could have been produced with those same resources.
Building a bridge means using up resources that could have been used building homes or a hospital. Going to college means using up vast amounts of resources that could be used for all sorts of other things.
Prices force people to economize. Subsidizing prices enables people to take more resources away from other uses without having to weigh the real cost.
Without market prices that convey the real costs of resources denied to alternative users, people waste.
That was the basic reason why Soviet industries used more electricity than American industries to produce a smaller output than American industries produced. That is why they used more steel and cement to produce less than Japan or Germany produced when making things that required steel and cement.
