No one can read the future mate.
Your best bet is to remain flexible, do research and when the country you move to tanks hop onto another.
I have been told UAE is a solid Moneymaker, decent living in Thailand and Indonesia, Vietnam is on the upswing right now but I know their tech sector is flooded with locals so competition will be brutal.
I would avoid China as they are getting primed for their own financial collaspe and if it happens your head will go on a pike just for being a forigener.
Likewise I would avoid Saudi Arabia for its impending civil problems despite the ability to make good cash there.
You probably want to avoid Japan and Korea as they are both difficult to get work for and if you are doing non-English Teaching work you will have to put up with their brutal work culture and their immense Gynocentrism problems (slated to get worse of course).
For the same reason I would be careful when picking a Western nation like the US, Australia, or most of Europe.
But you can make good money in the short run to give you a better buffer when it is time to jump ship again.
Anyone feel free to correct me if I am wrong as I don't know much in depth about most countries outside of far East Asia.
