So? Imagine yourself 500 years ago born in a peasant family. You work on the farm, you are tired and the work is boring. What will you do about that? You don't have much choices. You can find yourself a cheap hobby, drink a lot of alcohol, try a career in crime, or join an army and probably die. Does the fact that you are bored like hell change the economy? No.

Even if a way out exists, people are not automatically strategic, so many will not find it. They may also stay on their place because of their social world, or because they are somehow convinced it is their duty, etc.
