I think that when people think on emmigrating as one of the most clear ways to react to problems they don't intend to start a revolution anywhere else. They just think that no matter if the problem is global and other countries have a worst structural perspective, the way the crisis will be handled at home will make it worse, so better go somewhere else...

"If you don't want a man unhappy politically, don't give him two sides to a question to worry him; give him one. Better yet, give him none." (Fahrenheit 451)
