I'm glad to see the questions rolling in :)
How many parents believe they should be allowed to hit kids?
If you mean smack them on the rump, then many.
Is the divorce rate as high as shown in the media?
The divorce rate is depressingly high, yes.
Do people in US know other languages than English? (learnt, not native)
Well, in my school, we are able to learn Spanish, French, and German (I took German). So a good percent of us have learned a second language. The hard part is remembering it after you graduate.
What do people think about having colonies around the world?
That's a good question. I don't know; it's never been a topic we talk about.
Do people prefer the pure Capitalist system, or the EU system? (free healthcare, education, etc)
Oh, we want free healthcare and education. I think we want free education more, and at least affordable healthcare.
