if they had had the luck to have an education, maybe they would know about condoms. You and Piot especially (keep it white?????) are narrow minded. You don't understand how the world works, how poor people think. Living in Mexico is probably like living in a treehouse in the garden of a palace, eventually you'd probably want to move in the palace if you had the chance. Sure, i'm down for educating immigrants, but not refusing them. And i'm not one of those smelly hippies.
There are some better things about the US, first of all the economy, your country is still prosperous because it allows everybody to start their own thing and get rich just like that. The US has probably a bigger diveristy of landscapes too. Canada rules though.
