You're missing the point.
Mexico is invading the US by stealth, and they are trying to get back the land the US took from them in the Mexican Session. They already have most of it back, and better yet, they are getting the states to pay for all the infrastructure.
Ai Caramba!
Oh, one question, how much do illeagals cost? Every body is talking about how much they cost. If they're not too expensive, maybe I might buy a few myself, I got this farm that needs maintaining, as well as several other businesses that could use a heap of cheap labour. And since there's no risk in it for me, and only a lot to gain, I say sheeeeeeeit! Go for it! With the tax breaks I get for the businesses, and the extra profits, I'd have to be stupid not to.
