I read once that if you took 50 American girls and 50 Russian girls and stood them up in a line naked it would be hard to tell them apart. (Assuming similar body shapes...I.E. the American girls were forced to cut down on the Ben & Jerry's.) The major difference between the American girls and the Russian girls is one of class. Russian women typically dress better and take better care of themselves than American women do.
Now, a lot of this is probably that it takes a bit more work and determination for Russians to come here, so their numbers are somewhat low. They can't just swim the Rio Grande and be home free. This leads to apex fallacy. We probably aren't seeing the Gopniks and other gutter scum coming over here, and of those that do, they don't really seem to make it as far as Nebraska. I was having a similar discussion with someone the other day. They asked why so many Indians are doctors, and in general seem like good people. The answer is simple, we aren't seeing all billion of them. Only the educated, upper caste ones. This is the same continent where some of the kindest, smartest, most beautiful people I have ever known have come from, and it is the place where a girl got raped to death with a piece or rebar. So, I can say that almost a hundred percent of the Russian women I have known have been beautiful (and stunningly so), classy, and educated. But I am sure there are some hideous ones who are dumber than a box of broken rocks.
