With respect to your first point, no, you simply don't understand.
I guess there could be details about revolutionary period that make it much different. It's been awhile seen I read alot about it.
With respect to your second point, the answer is none.
I should have said political consequences. Even if the senators you mentioned think they answer to illegal immigrants that doesn't change reality. Illegal immigrant have no way of replacing a senator that doesn't represent them. So in reality they are not being represented.
With respect to your third point, many items are not subject to sales taxex (I joined with former State Representative, and latter Democrat Party Chair John Kromko in working to sucessfully repeal the sales tax on food), and other can legally be avoided (buy you tobacco products on an indian reservation).
Food and tobacco aren't the only things illegal immigrants buy.
I guess I approached this thread in the wrong way. In some of the other immigration threads recently as well as this one a common theme I think your trying to stress is fairness for people who aren't illegal immigrants. One of the reasons I can't support ideas like those is the "injustice" happening is low income people receiving economic support. For me to be offended by that would take a different mind set than I'm comfortable taking.
To me people immigrating illegally are not that much different from the people who came for hundreds of years legally before there were any significant immigration laws. The passing of those laws is probably what potentially makes the economy fragile to mass immigration.
