I'm afraid that my answer would rely on a level of understanding of Eastern European political history that you lack. The notion of "jumping from" one system to another is absurd, and implies some sort of abstract equivalence between the two. (In fact, it diminishes the ravages of communism, and betrays a certain level of ignorance). Furthermore, your typical Eastern European would question whether your "concern" is genuine, given your piss-poor track-record in combatting socialism in your own backyard.
For the record, in my opinion, the developing economies of Eastern Europe likely will settle upon a socio-economic model similar to that of the Scandanavians. So if you were looking for a glorious free-market savior, then you'll have to look elsewhere. If you merely seek to warn of the dangers of socialism, then so what?
