What I don't understand, probably never will understand; is that these people are living in places of opportunity. For the most part their parents immigrated to France and these youths were born in France, schooled in France, etc. They have the information to sort through both the facts from the fiction of life and they choose the philosophy of poverty. A philosophy that will leave them poor and angry. What can cause such a skewing of their vision for the future? If one chooses to follow a lifepath that leads to deadends and you refuse to turn around it is not on the backs of others to save you.
You just described a rather large chunk of the American population.
