I would think long and hard about spending years in a foreign country. While admittedly I haven't done so myself, I've traveled to some of the kinds of countries you're thinking of and talked to and observed expats in those places and it seems awfully lonely. There's a cultural and, I assume, language barriers that'll make you feel like an outsider. You may find a community of others like yourself, but still you're likely to struggle to make meaningful relationships. Sure, working for the man sucks. But I'd argue crushing loneliness might be worse.

Of course I'm applying my wants/needs and my experiences to your situation. Maybe that's not a concern for you. Maybe it'll be the best thing you ever did. But it warrants consideration. The grass isn't always greener on the other side.

Also something to be mindful of is in some countries foreign individuals can't own land.
