The labor market (how to get money if you don't have enough) creates a perverse incentive. I wonder if anyone has reaearched the "volunteers" and their position in both labor and wealth.

I wonder why I never hear this argument applied to government spending in general. In non-authoritarian countries, spending money is the primary means for the government to inflict their will on the public, regardless whether it will have a positive impact on society.

I think it's a question of "treat the symptom" sometimes as well. Some people really cannot make ends meet due to their locality and don't deserve to be stiffed by a migratory economy.

they are being forced by statistics. It's a supply/demand problem. If you get people in a bad economical situation and then give them enough money you will get them to do your thing. Just increase the amount of money until you get enough people signing up.
