Under our present system the cost of illegal immigration is created chiefly buy the children of the illegal immigrants.
The abuse of illegal immigration can remedied by our present immigration regulations should the federal government choose to enforce them.
"No change in the structure of the tax system can offset the cost of illegal immigration."
Quite true. The cost of illegal immigration is $40,000 per person, per year. There is just no way a 15% or 18% tax on some merchandise can make up for that $40,000 per person per year.
