I Russia still socialist? That depends on how we define "socialist", doesn't it?
My own opinion is that these kind of words, so vague in their precise meaning and so loaded with emotional connotations, aren't very helpful.
Russia seems to me to best approximate the old late 19th century German/Prussian model. This was a system in which private enterprise was encouraged, but steered by the government so as to achieve ends deemed to be of national importance. In Prussia that was basically the needs of the military. So Germany developed heavy industry so as to better foster war production, it built up Europe's best rail system, so as to move military material, and it developed a strong banking system to fund it all. Private enterprise was encouraged to innovate and was rewarded lavishly if it did so successfully. Economically speaking, Hitler's Reich was basically just an attempt to restore that successful 19th century system and Germany's rapid resurgence in the 1930's was evidence that it worked.
Today China is probably the best example of that system in practice. And that's the direction that I see Russia taking.
Whether somebody chooses to call it "socialism" or "fascism" is largely irrelevant in my opinion, merely an expression of whether or not the speaker approves.
