Yes, the schools are fine. But not as good as in the countries surrounding it, and since moving within europe is cheap and relatively easy why not go for one of the best. I've yet to meet a parent that did not want to give their children the most opportunity possible. Combined with the limited opportunity in the local economy, the fact that the quality of life is still far behind nearby countries I really don't fault them.

It's a pity for the former sovblock countries, they still experience a lot of brain-drain due to causes like these and that likely will continue for a long time. Those wounds inflicted by 5 decades of mis-management are quite serious and healing them will take a long time. Possibly a multiple of how long it took to inflict them in the first place. And the further east you go the worse it gets.
