I meet so many Americans that say something like : "You want to stay, become legal".
Off course I want to be legal dumbkuff.
Few are aware that being legal is not as simple as "go pay several grands to a layer, or find someone to sponsor you". Since Sept11, immigration laws do not allow you to become legal even if someone wishes to hire you. The "only" way is to get married. Especially in aviation where Work Visas are not accepted.
As I said, you do not quite have a choice. You are not offered the opportunity to straighten out, thus you stay illegal. Thus you don't pay taxes, you drive without insurance, you drive without a driving licence, and all the bad stuff.
Claim "go home" all you want, those guys left their country, and are picking cheries for $4/h, while their wife clean your restrooms. They are here to stay, "go home" is not going to impress them.
The Latino comunauty is fairly well known for helping each other, and is a fairy significant work force in USA. I agree they have no right to protest, but they have a political power, after all the Mayor of L.A. is Latino.
