That of course leads some doctors to refuse to take on new Medicare patients. But this process takes time to really make its full impact felt -- and elections are held in the short run. This is another growing problem that can be left for someone else to try to cope with in future years.
Increasing amounts of paperwork for doctors in welfare states with government-run medical care, and reduced payments to those doctors, in order to stave off the day of bankruptcy, mean that the medical profession is likely to attract fewer of the brightest young people who have other occupations available to them -- paying more money and having fewer hassles. But this too is a long-run problem -- and elections are still held in the short run.
Eventually, all these long-run problems can catch up with the wonderful-sounding lies that are the lifeblood of welfare state politics. But there can be a lot of elections between now and eventually -- and those who are good at political lies can win a lot of those elections.
As the day of reckoning approaches, there are a number of ways of seeming to overcome the crisis. If the government is running out of money, it can print more money. That does not make the country any richer, but it quietly transfers part of the value of existing money from people's savings and income to the government, whose newly printed money is worth just as much as the money that people worked for and saved.
Printing more money means inflation -- and inflation is a quiet lie, by which a government can keep its promises on paper, but with money worth much less than when the promises were made.
Is it so surprising voters with unrealistic hopes elect politicians who lie about being able to fulfill those hopes?
