The problem of the countries in eastern Europe is primarily political corruption, rooted from the old soviet system and slowing dying off.

But, this is being resolved by: People moving to other countries resulting in a decrease in government tax revenue, giving less incentive to extort money through corruption and forces efficiency on government services (out of necessity), and in the end, it makes it a competitive market again.

People like my parents who left will never go back. But for people like me, if the conditions in those countries improve and become attractive again (and they seem to be improving), I have no problem with going back.
