There are something like 3 women for every man in Russia. Seriously, if you look up the data for it. It's due to alcoholism, among other things.
My Russian girl who lives just outside of Moscow confirmed this when I asked her about it. Thus, many of the breathtaking Russian women you see don't necessarily have a choice; for a Russian woman to have a man in her life in Russia is advantageous I think, regardless of his looks.
Also because, based on my observations, in Russia if you're a woman who is 30+ and unmarried, not many guys want you, because they can get one 30-, if not 25- too.
