Just to provide a concrete scenario, let's assume that in your current country you (magically) have a decent-ish job. They open up offices in another country of your choosing, and you have the option of moving there and work for an equivalent living wage.
They're able to get visas set up (however improbable that may be) for you and any family, but you have to go through the process of finding housing, physically moving your belongings and anything else you need to set up.
What countries would you take the offer to move to, if any?
If you want to keep living like a slave you can try a 1st world country, if you want to find out how much shit you can buy with some dollars move to a third world country.
Personally I moved to a third world country and I'm doing pretty fine, you can always spend in some extra security and you should be fine.
USDs can do a lot of shit when you move to an America worshipping country.
Edit: According to the premise of your first post I suppose you are talking about someone who it's already a slave in the US, if you doesn't have any debt and you are making good money I suppose you are capable to move to any country.
WO mention even natives treat you better if you are American, IDK I believe they have seen too much Hollywood shit or whatever.
Avoid any communist country btw they don't like Americans.
