Why are we educating Mexican children in Texas?

According to this story, about 650 Mexican kids who reside with their families in Mexico cross our border every day to attend American schools in Roma, Texas.
A local TV news channel recently reported that these kids were crossing every day to take advantage of the superior education offered in our schools vs. the Mexican school system because we have no border controls in Roma, Texas. So who else is crossing that border every day, and where else do they cross? If there are 650 kids sucking up our education tax dollars just in Roma, how many do we have doing this in other border towns? And these aren't even kids of illegal aliens--these are straight-up Mexican kids who just come over the border every day for the education and free school lunch programs that you and I pay for. Per the story, it costs $7,000 to educate one child, and for 650 kids, that's $4,550,000 a year spent just in Roma on kids who aren't even ours! How much do you think it's costing us nationwide?

Now this is allowed to take place because we haven't closed our border or even pretended to be watching it. (Thanks, Congress and President Bush!) But it's also happening because school officials are for some stupid reason forbidden from asking about the students' citizenship. All a Mexican parent needs to do is claim local residency one time, even via an address of a friend or relative here, and the kid is accepted all the way through 12th grade.

And it's not like these kids come over fluent in English. They don't speak our language, so they bog down the classes for the legitimate American kids who do and they require the schools to go out and find Spanish-speaking teachers, again at our expense. (That's more money allocated for but not being spent on the American kids who actually belong in those schools.) And ironically, because demand is so high, and the number of American Spanish-speaking teachers is so low, many of our schools from Florida all the way across our southern border and up the west coast to Oregon and Washington State, are now hiring Mexican teachers to come here and teach the Mexican kids. In OUR schools. At our expense. The Mexican government of course pays nothing for this and acts offended when we discuss it or propose stopping it.

I'm thinking that it's time for our military to seize two or three hundred miles of Mexican territory immediately south of our border. We need to drive every last person out of that strip, tear up all of the roads and raze every structure there, and essentially create a buffer zone that will make it much harder for invaders to cross over into our country. Little kids, drug mules or terrorists, I really don't care. I just want our border secure and our country and it's people, resources and jobs made safe.
