I wonder if most of their best and brightest are all over here now. I've worked with a lot of Russians and to a person they've been smart, hard working, and tough. Stubborn as rocks, too, which can cause some problems at work sometimes but their tenacity is more often an asset.
I don't know why their former country is such a mess unless all the sharp and innovative ones have left, or if the system is just so completely hosed up that they can't make a dent if they stay.
We have several Russian families in my subdivision ... 3-5 children each, some with grandparents at home, and the parents have tech-industry jobs. Aside from one old guy who doesn't speak English and gets drunk in his garage, they're good neighbors.
