Speaking as someone from Poland/EU, which is heading in the opposite direction...

Many people seem to be complaining about certain absurd EU regulations that were forced upon us.

I, for one, am extremely happy - centralised government has saved us from a lot of absurd ideas the local policymakers had. Also, we have one extra level of courts, where you can go when your government breaks law.

Not to mention all the benefits for commerce and travel - knowing that other EU states have similar laws and standards helps a lot.
