Actually, it's the France who wanted EU to spend 100 miliards Euro on each eastern european country in order to save hungary & few other countries(such as Baltic states) from bankrupcy. Happily, it was abandoned after intervention from Polish & Czech prime ministers. But Europe can afford such actions.
Complains started when some of the newest countires of EU (mentioned above) went bankrupt, and after Romania rendered to have big problems with corruption. Other states are doing quite well.
Not really, for UK it's actually beneficial, as it sucks out the best cadres from e.european countries and gets good and cheap workforce. Germany doesn't allow e-Europeans to work in their country, so they don't have much problems with that- instead, their biggest problem is growing Turkish and Muslims population.
And Italy have problems with Balkan Romas, (Tsigani), not with e-Europeans.
No. It's based on it's activity in EU, economics and population. In all those, France is superior to Poland. So I can live with that.
Which parliament isn't?

But that's the problem of EU citzens, who are voting for incompetent/incapable members.
