The truly cruel and heartless act would be to permit the Mexican invasion to turn the southern US states into an extension of the socialist, corrupt, drug-gang anarchy that is present day Mexico. Open-borders proponents advocate a policy that would kill American prosperity. One only has to look at the budget disasters in California and New Mexico and the violence along the border in Texas and Arizona to see the brutal reality of this predictable catastrophe.
Good post and correct. You note the tri-fold problem with immigration - criminality/corruption (not just the act of immigrating, but true crimes), the welfare state, and bad immigration policy.
