That is pretty comical. Unskilled? Obviously, you have never witnessed a field worker, rather it is picking tomatoes, strawberries, or maintaining Christmas trees. Many of the NASCAR drivers around here have horses, it is illegals that tend those horses, they are the best Llaneros by far. Getting body work done on your car in Texas, yep, it is illegals, doing the work, the entire industry there depends on them. The meat packers in the Midwest, they bus them in, and when they cut off their fingers, they ship them back to Mexico, avoid the workman's comp claim.
Semi-literate? Well yeah, their English might not be that great, but if speaking English was a requirement we would be singing God Save the King before every baseball game. In my neck of the woods, the schools didn't start teaching in English until the middle of the 19th century. German was the most common language, and Cherokee was second. English placed a distant third.
Law breaking, that one is the most comical of all. Here is the deal, increase the number of illegal immigrants in a population and you actually see a decrease, A DECREASE, in the violent crime rate.
