That's simply not true -- there is a reason why trades have apprenticeships, journeyman, and master levels. The fact that you can put a toilet in doesn't make you a master plumber. Immigrant labor floods the low end of the market and starves off the supply of new laborers to the higher end because there's no career path for an illegal, casual worker. That's why a skilled master plumber often can get away with charging $150/hr. Frankly, white collar jobs like IT are if anything, easier than most trade jobs. Get me someone who can read at a high school level with a reasonable work ethic, and I'll show you a very good IT Pro in 3-5 years. Ditto for programming.
