We all know it's true. Illegal immigration is an economic issue. It drives down the cost of labor and services and hence the cost of many products as well. Large segments of our agricultural sector are more or less built from the ground up to require undocumented labor. Domestic help is to a huge extent illegal. Home child care, housekeeping services and gardening is extensively performed by illegal immigrant labor, as is home renovation and repair. Illegal labor pervades other sectors like restaurant and food service and so on. The net effect is that it drives down wages for unskilled and semi-skilled labor and to some extent for salary and wages up the chain of training and skills as well. As a brake on the cost of labor, it becomes a generalized brake on inflation and the cost of many consumer goods and services in the economy. Like the Wal-Mart effect, it has been a driver of consumer spending. Keep in mind that illegal immigrants are consumers too and contribute to the economy by spending much of what they earn in the economy. Illegal immigrant labor thus supports the jobs of U.S. citizens. Illegal immigration is a social infrastructure issue. Illegal immigration represent a burden on social services, on healthcare. It's also true that while many illegal immigrants don't pay income tax, many of them do end up paying social security/Medicare taxes that don't benefit them, and of course they pay sales taxes like everyone else. Illegal immigrants pose a burden on infrastructure - they put wear on roads and highways, they add to the burden of municipal services like water and sewage and the electrical grid, waste disposal. Illegal immigration is an environmental issue. The country that cannot control its population growth cannot control its environmental future. The bottom line is that nothing will be done about immigration because the middle class benefits from its effect on consumer prices for goods and services, while the upper classes directly benefit from the effect it has on suppressing the cost of labor. The only people who lose directly are lower income Americans whose wages are most affected by the low end price competition for their labor. Sorry, but we'll need a much worse recession than the one we're trying to recover from before anything significant happens on immigration reform.
