And there's probably no single reason why the history is the way it is. It's absolutely not like "Soviets were there and that's why it is the way it is". There's probably not even two or three or four reasons why - but some complex set of causes and effects that led the world to where it is today.
Don't get me wrong, please. I'm not absolving the responsibility by blaming Soviets for Russian problems. I'm just mentioning one of the potential factors, saying that Soviets had contributed to this.
Soviet legacy is probably way less important than Putin's years. Since USSR fell, Ukrainian people had elected 6 presidents, and Russia had something like two and a half, all hereditary preemniks to each other (and - again - that's not a particular reason why things are the way they are, just another indicator of how different two post-Soviet countries are).
I guess, I should've been more concise and just said that in an atomized society, uprising is considered to be an unlikely event - without trying to delve into reasons why Russian society is atomized.
