Tim, I give you complete credit for being consistent in your views, but it is sort of an exercise in futility to discuss this issue with you. You are an open borders guy and that is something I vehement oppose.
Illegals or whatever you want to call them cost America as a whole and no other area is this seen than education, My wife has been in education for over 25 years and the absolute drain it costs to our educational system is staggering. The need for more and more and more interpreter services is just one example. The budgets for school districts is already strained and I know this is one area of need that is just exploding. When you have special needs kids that come from undocumented individuals--it is a lost cause. My wife will arrange IEPs that require home intervention and the parents will just blow her off because they don't speak English and are making zero effort to learn it--which they need to do to help their Americanized kids. Standardized test scores (which alot of time affect school funding) are lower with undocumented students from Mexico because of the language barriers. Having to provide bilingual literature costs money that these school districts don't have and should be going to make American students better.
You quote violent offense numbers and you may be right about this, but the amount of court intervention with undocumented people is extreme. I have challenged you in the past to go to your local courthouse and see all the efforts the judicial system has to expend to address these people. Our interpreter budget has risen 10 fold and that has come at the expense of many other programs that would have benefited Americans. Traffic court is a mess--most, if not all, do not have a driver's license or insurance (but again we should probably let bygones be bygones with illegals because they WANT to be here). I don't have the site but I will find it, the amount of traffic fatalities caused by undocumented individuals is disproportionately large--which makes sense because they don't understand the street signs or the rules of the road. A large percentage of them, after being found guilty of offenses, simply blow the fines off because they go to Mexico and magically come back as Gonzales-Hernandez or Hernandez-Gonzalez and there is zero way to link them or initiate collection activity. ID theft as has been mentioned before, is rampant with the undocumented. DHS services for undocumented kids from abusive household is another area where the American tax payers eat the cost as American parents charged with this are hit with the costs to reimburse placement services, there is no way to collect against the undocumented parents. Again Judicial districts having to provide everything in a bi-lingual format cost money.
I can post more re: Stem jobs lost by American students to visa holders, medical costs incurred by Undocumented medical bills at ERs that are left unpaid, but I have to go to dinner here. I think we can find a middle ground on how to fix it.
Bottom line: I want a lamborghini, there is literally no path for me to obtain one, but I don't get to take it. Coming to American is not a right---maybe stay and make your own country better. Be the change for where you live and stop expecting others to conform, change and pay for your what you want.
