If you can't leave your country, the whole further debate on advantages or disadvantages of its system is pointless, isn't it?
At least for the people living in that country, that is.
Because intellectuals worldwide will happily waste air debating how great that country is, and well, inability to leave it is a small price to pay.
And of course it's small, because they aren't those who pay it. Those who do pay it aren't even part of the debate.
