Watching the dilapidation that has accompanied mass illegal Mexican migration has soured me on them.

You should check out previously black neighborhoods. Illegal Mexicans moving into black neighborhoods has led to massive gentrification in them.

Compton went from being 90%+ black to 70%+ Hispanic (almost entirely illegals) in the past decade, and the crime rate dropped, property values went up, grades have improved, local government corruption has fallen, new businesses opened up, etc.

Which is not to say that illegal immigrants do a great job, but don’t forget the bar can always be lower.
