There is a generous reward system for illegals infiltrating our country: their babies get citizenship, they get free health care and welfare, and too many employers are willing to hire them “under the table.”
Serious immigration reform would address those issues. Tightening up border security is inadequate to preventing illegal infiltration when there are pots of gold waiting for the successful infiltrators.
I think that the value of ending the anchor baby practice does not need to be spelled out. The free medical care can be addressed by 1) providing care only for matters of life, limbs, eyesight, and 2) sending the bill to the illegal’s country of citizenship (perhaps deducting it from “foreign aid” payments). Under-the-table hiring can be opposed by 1) auditing employers, and 2) ending minimum wage laws, since those laws provide incentive to try to get cheaper unskilled labor.
