why are Russians so good at chess

Add in guys like Sevian and Awonder Liang and you have more on the way.
Being a new member and chess player explain in this case what "home grown" means. I take it to mean they suddenly showed up and were contenders. Thanks.
Not only Russians are good at chess but European people, in general, are very good at chess. The United States focuses more on sports like soccer, basketball, tennis, football, and other sports. Chess is an odd sport that the United States does not care about. I think that in Europe, sports probably are not that popular and not interesting than in the United States.
This rubbish answer was picked out by Google in my search query "are russians still good at chess?"
Google should be finding better sources than a forum post.
