EU as a block Economy-wise against China or the US is necessary to remain a top possition in this world! If not every single country would'nt be able to rival for example China!
So in that way, i think it's good, and necessary!
Bad things about the EU (I'm from The Netherlands btw):
-EU doesn't want us to take the lead in greenhouse friendly technologies cuzz then it'd be 'false competition' for foreign companies which would be unable to compete with us. (Example: Filters for greenhousegas emissions in cars, European court overruled our governments decision).
Opening of borders also is bad for us cuzz 20 years ago, LOADS of people came from Marocco or Turkey etc to our country. A lot of the kids those people got hate us and The Netherlands... Don't ask me why cuzz they took full advantage of our wealth and are still complaining... Pfff... But now, the same thing is happening with people from Eastern Europe!... (Btw: I don't hate those people in any way...)
Another good thing about the EU though is the Euro's strengh on the Ww market (Dollar is dying, FAST! Muhahahaha 
)...
But The Euro made our prices go up WAY too much!... I think that's really sad cuzz our government 'ensured' us that that wouldn't happen.
