This is certainly not true. I do not know where you get it from, but real brain drain started after transition to a presumably better capitalist democratic system and it happened due to economic reasons. The funding simply went down by orders of magnitude, which made scientific work impossible.

Your personal tourist impressions are not making you closer to understanding of such a big country with such complicated history. Try reading some books if you are really interested.

I have read books, of course. But brain drainage for sure were prior the dissolution. You can read for example about the Operation Osoaviakhim, where 2500 scientists (and their families) were forced to go the soviet union as war reparations. Or the book The Murder of Nikolai Vavilov: The Story of the Persecution of One of the Great Scientists, were you can read how beautiful was science in the soviet union.

The real brain drain started when people were finally allowed to flee the paradise and what was left of it. It wasn't their fault your apparatchiks and yesterday's party members, the real owners of everything, started to carve up their posessions calling themselves capitalists this time. Before the fall only establishment members could flee (illegally) and jews (since the 1970s).
