Are you seriously suggesting that everyone who doesn't like the way his country is ran should just leave?
Just sever the ties that link them to the homeland - to the relatives, the job, the environment they grew up in - the culture, language, the graves of ancestors - leave behind the old friends and old enemies, take their family and memories and become... who?
A fugitive? Unwelcome guest? Jobless, homeless, at the mercy of international organizations, with unclear prospects and still a family to care for.
Of course there are those who managed to build a new life after leaving their country. After a time, most emigrees adapt. But at what cost? How many nights sleepless from worry, how many insults thrown at them and their children, how many degrading job interviews where your exotic medical diploma is worth less than a local plumber's certificate?
And that's after one manages to flee the country, not a simple task in itself.
You have no idea what you are talking about.
