Maybe 3rd world countries could start opening up their citizenship/PRs for US/Western Europe/Canada/Japan/Korea/1st world citizens. i.e, Give up your origin citizenship, say US, for Indonesia for example (because Indonesia doesn't allow dual citizenship), and gain these benefits for you:
- Extremely cheap cost of living
- You can own a house and a yard as big as you want, with nice cars, and maids, drivers, gardeners
- You can send your kids to international school that are cheaper than your private school, and also of better quality education wise than your local public school
Meanwhile, Indonesia will gain:
- The new citizens/PRs can help create opportunities/businesses in Indonesia and employ locals
- The new citizens/PRs will spend their money in Indonesia, buying local goods and services
For example, a nice area in Serpong (just a bit south of Jakarta, cluster-style 2 story houses, 3 bedrooms, will cost you around $150.000. Complete with security guards.
I'm sure there are other countries that are ok too, like Thailand, Vietnam, Philiphines.
