The dissidents still stuck in Russia are for the most part people that would not be able to succeed at all in Europe. Big name scientists left during the 90s, people who succeeded economically started leaving post 2008(once Putin/bureaucrats started clamping down on free business) and the last of both groups got out once the conflict started.
I mean at this point in time most European/ex-USSR countries have put measures in place to prevent dissenters escaping there, so it also isn't easy even if you do have skills.
