Certain groups in England may be thus impoverished but Christopher Hitchens certainly isn't, nor English film-makers who are currently the world's best, nor many, many others.
That is besides the point. The point that I have been making is the number one cause of poverty is culture, most particularly, the breakdown of marriage. The only reason England is even remotely interesting is that it is an overwhelmingly white country, thus you can talk about poverty without race entering the equation.
