Interesting how all of the "jobs American's won't do" are jobs Americans used to do. The only difference is that the welfare state now allows people to stay where they are rather than pursuing opportunity.
People once migrated across the country for jobs. Today, it happens but to far less an extent. It seems that people are more likely to come to this country than natives are to move. Immigrants take risks. They do not use the excuses. At least that used to be the case. Now, nearly 60% of immigrants receive some sort of federal welfare. According to the Center for Immigration Studies "In 2009 (based on data collected in 2010), 57 percent of households headed by an immigrant (legal and illegal) with children (under 18) used at least one welfare program, compared to 39 percent for native households with children."
So, the welfare state's cost goes beyond dollars and cents. The welfare state costs us in work ethic. It costs us when young people don't see their parents and grow up hopeless and dependent. It exacerbates our immigration problem. The permanency of the modern underclass is a factor of the federal government's welfare state.
