1.- I would assume that it would lead to a recession when coupled with a huge chunk of the labor force leaving the workforce. I think
@Jack V Savage would provide a better picture.
2.- Most definitively, kicking illegals out would generate a hike on prices in a lot of consumer goods, except in real estate.
3.- Because remittances are not physical things being extracted, remittances are untangential IOUs that exist only in the abstract mind, when jose sends remitttances to his family in latin america, he isnt sending actual wealth, he is actually sending paper money, paper money that would be ultimately useless if not spent on American goods and services.
4.- Not really, for example oil prices, America is one of the largest producers of oil, but its also a net importer. So high oil prices are bad for the economy, but really good for oil producing regions of the US.
So bad for the national economy but good for the local economy.
