It's not the Lump of Labor fallacy to say that the economy has a limited appetite for low-skilled workers. In Australia, where illegal immigration is quite limited, it's not a choice of Wal-Mart and the gas station for folks without white-collar skills, there's also farming jobs, cleaning jobs, and best of all, tradesman jobs like builder, electrician or plumber. You'll need an apprenticeship for some of those, but can quickly work your way up from earning very little as an apprentice to earning six figures as a competent and fully-qualified tradesman. But in America, all the job categories which I mentioned are dominated by illegals, so it really is true that the uneducated have a really rough time.
