Isn't it kind of a scam to lure wealthy citizens to their own nation or is it a genuine effort on their part to safeguard these people from exploitation?
On the other hand, if American and European countries started to reverse exploit this situation they could really enter less developed nations with ease. Per capita income in US is above 100,000 usd so they wouldn't have a problem becoming international citizens of the world while Africans with less than 2$ per day and 600$ per day become stuck due to mobility and lack of education?
