That's a fantastic question. I'm not sure that I've seen good polling. First of all, it's hard to do good polling in Russia, for a lot of reasons. I will go and check to see whether anyone is asking that question of Russians and what kinds of answers they get.
My guess is that most Russians don't think their children will live better than they do. That would be my first guess. Whether they think their children are going to live worse, I don't know. I also think that the expectation of each generation living better doesn't exist in Russia in the way that it does in the west.
