"Hanson analyzed how the size of the undocumented population and its use of public assistance affected attitudes toward immigration. He found that among low-skilled workers, opposition to immigration stemmed mainly from the competitive threat posed by the newcomers. Among high-skilled, better-educated employees, however, opposition was strongest in states with both high numbers of immigrants and relatively generous social services. What worried them most, in other words, was the fiscal burden of immigration."
The irony is that for all the overexcited debate, the net effect of immigration is minimal (about a one tenth of 1 percent gain in gross domestic product, according to Hanson)."
This last contention that adverse consequences are minimal, illustrates the withdrawal from reality of defenders for the latest Obama unconstitutional initiative to eliminate the rule of law.
