No doubt in which country I would prefer my children to grew up in.
Economically the northern and western european countries are still ahead of the eastern european countries. However, in quality of life no longer.
A polish computer science colleague just told me the other day that he will move back to Poland with his family. One technologic boomtown in Poland is Wroclaw (Breslau). Especially many foreign software companies as well as banks (IT outsourcing) have invested and are investing heavily in that polish town/region (Schlesien).
