Immigrating to another country means becoming a citizen, not just buying a house for when they are on vacation or business. Westerners who buy property in the Emirates are not immigrating there or becoming citizens. Many westerners have property in the carribean but they have not 'moved' there.......so no cigar!
Your ideas about wealth are symptomatic of your vile, convoluted religion. Wealth is NOT evil or noble. It is just money. Money is a blessing to a good man and the downfall of a bad one. Study the REAL bible (torah) and you'll learn that. Wealth of production is also a good measure of the merrit of a country's culture. Japan has a seperior culture to Nth Korea....therefor, it is richer. As is Switzerland to Albania etc.
