MBM ... I don't have time to comment on your post above right now (and I will, because I actually agree with what you said at the end! ), but I'd like to ask you just two quick questions, if I may:
#1 - Have you ever lived in a state that border's Mexico? If so, which one and for how long?
#2 - Please go out on a hypothetical limb with me for a moment .... do you believe that if illegal Mexican immigrants in this country today were denied the educational/medical/housing/social benefits and services that they are currently allowed to utilize ... would they continue to come here, stay here and work here under the same conditions they are living and working under now?
