Why problems never seem to be fixed.

Have you ever wondered why bad economic policies, like New York City rent control law, seem to stay on the books forever and cannot be changed? We know that price controls only lead to shortages and price floors lead to surpluses. So why keep rent control when it will lead to housing shortage or limit the number of taxis in a city to a low number so the taxi licenses cost several times more then the car? Well William Tucker at The American Spectator has an interesting idea on why this is.
