The moment we land on other planets or traveling around the earth takes less than an hour, there will be less and less reasons for people living in these countries having to cope with their cultures and eventually choose easily where they want to be among.

The problem with that is that people migrate all the time, go to other places to have abetter life, but bring their culture too and instead of trying to fit in and be part of the new culture, they try to live how they lived at home. Would not necessarily be a problem, but when they want to impose their culture and (bad) habits on the new society, you know it was not the place and the environment the problem at home, but them. When you emigrate to a new country to have a better life and once there, the only thing you're after is looking for shortcuts, handouts and committing crimes, you are the problem.

Anyway, let's hope life is going to be way better for the next generations.
