Ignorancia económica y voto racional

John Stossel sobre por qué tanta gente vota políticos y políticas tan nefastas:

I'm not alone in this concern. An economist at George Mason University, Bryan Caplan, says few people think about their vote or even see any benefit in doing so. His new book, "The Myth of the Rational Voter: Why Democracies Choose Bad Policies" , argues that most voters cast their ballot on the basis of irrational biases about economic matters. That's why so many candidates hostile to free markets, profits, free world trade and immigration get elected. People tend to acquire their wrong opinions about economic policy packaged in worldviews they inherited while growing up. They never test their views against the evidence because that would be unsettling. No one likes having his worldview challenged. So people vote for candidates who make them feel good. They vote irrationally.

Caplan stresses that most voters see no reason to do otherwise because they don't bear the consequences of their choices. This irrationality does not carry over into their personal lives because there they bear the brunt of their own decisions. But when irrationality is free, notes Caplan, people will indulge their biases.

Caplan divides them into three categories: antimarket bias, antiforeign bias, make-work bias and pessimistic bias. Antimarket bias describes people feeling that trade and profit are zero-sum games, that one person's gain is another person's loss. They haven't learned that free exchange is win-win and that in a free market, profit comes from cost-cutting innovation. Antiforeign bias, perhaps a vestige of primitive man, consists of distrusting "them" even though our prosperity increases according to how global the division of labor is. Foreigners don't want to invade us; they want to sell us useful things. Make-work bias is the belief that what makes us rich is jobs, rather than goods, and so anything that eliminates jobs is bad. If that were really true, we could prosper by outlawing all inventions created after 1920. Think of all the jobs that would create! Finally, pessimistic bias is the view that any economic problem is proof of general decline. Lots of people actually think we're poorer than our grandparents were!
