If you don't think Northern Californians are at all effected by illegal immigration, then you are completely mistaken.
And... paying taxes to bring American students (Those kids are born in America, and that's the only way that works) isn't exactly what I'd call a terrible thing. I mean, look up Point Roberts, WA. They bus those kids in WAY further every day, but nobody in Bellingham is bitching.
And if you want to see businesses and people suffering, go over the border and see what American weapons and policies have done to that nation. America is just as at-fault for the immigration problem as is Mexico's own self-inflicted issues.
Have a nice day, Bluename.
