What is connection between Detroit and Green Card? I'd say,Detroit is exactly an outcome of excessive reliance on foreign intellectual force for building and sustaining economy. Foreign intellectual force has a nasty habit fleeing home or to some other country, (for example, one up north), in case of economic downturn in the country; and that accelerates downturn really badly.Especially bad, that accumulated knowledge is also carried out of the country together with H1B-guys. Corollary: no matter how arrogant Americans are about their country the standards of living are not highest there, and with worsening of the economy exodus will grow bigger and bigger..
