And why won't a fence work? We certainly have the engineering know-how to construct one. Are you afraid the Mexicans will call us names?
I agree that they shouldn't be on welfare, but that is up to the states. California is generous, Texas much less so. As for schools if they aren't paying property taxes, no school. Most are probably paying property taxes since they are living in apartments where the tax is included in the rent. If they go to school, they should be taught in English. California passed such an intiative a few years ago.
Like it or not we are going to have to deal with Mexico, you just can't wish it away. Heck even Sabertooth himself said that a wall is not a good idea.
Not to mention cheap labor too.
