There are exchange students from foreign countries. How about "exchange permanent citizens?" A friend of mine came up with this idea.
Lots of people want to come to America. Many think they can still make a fortune even though this is getting harder. At the same time, there are lots of Americans who wish to get away from the rat race. Chill out in the slower pace of some foreign nation. Many retired folks who would bring their retirement incomes with them. In some cases folks can no longer afford to live in America anyway. Look at real estate prices, health care costs.
How about exchanging places with someone from Costa Rica? An American moves there to slow down while a Costa Rican comes here. How about exchanging places with someone from New Zealand?
My friend is suffering from what some people might call "blue state blues." Not happy with the current direction of American society under George Bush. The so called blue states voted for John Kerry. Some have considered leaving America. Going to Canada, for instance. Problem is, Canada can not absorb all that population increase easily. Immigration to Canada is very limited.
This friend of mine suggested the "exchange citizens" idea.
It is worth thinking about, but would have some bugs. Some countries would be a lot more popular than others. It's an idea worth considering as immigration policy and quotas are negotiated between nations.
Also, I hope most of the blue state people stay here. We need them to keep America from jumping off the deep end.
