I just think some of the girls should train outside Russia for convenience for being the number one girl in their own stable. Nastya could be that outside of Russia. I am two years Eteri may have twice as many great skaters as she does now. Where are they all going to go? Some will go elsewhere in or out of Russia and Evgenia has paved the way. I know money is an issue but most of these skaters and their families know people who are wealthy. If I had money and by that I mean Millions and I only have thousands like most people I would want to support or contribute to support of some talented kid and give them a chance to become the best they can be.
Russian millionaire, if anything, would fund their training in Russia, as in fact some of them do. Quite a few girls that do not make the national team receive support from sponsors - because most of the government funding goes to the ones in the main team or reserve, really. Everybody else must pay for quite a few stuff from their own pocket.
Keep in mind that patriotism is fashionable in Russia, and we have the best ladies coach in the world, so it sort of wouldnt make sense for some rich person to risk reputation losses just to send someone abroad with unknown result. And put unknown on that result: Russian coaching style is much different from the western one, as it has been said multiple times across multiple interviews. There is no guarantee that a russian skater will quickly (or at all) adapt to the western style, even a top skater, because it requires a whole different mindset.
Honestly, the only way any of those B/C girls would go train abroad is if there is a millionaire, but not a Russian one. Kind of Kurakova style, where a polish sponsor sort of "bought" a good skater to represent Poland and funds her training.
