> You assume that middle class Americans are willing, available and able to do those jobs when paid higher wages and benefits. In my many years I have yet to find “Americans” doing roofing jobs for example. One would have to assume that eventually, when roofers are paid as much as those of us who are sitting here reading hackernews, there will be a steady stream of workers inclined to fill these positions. I feel like this is the sort of textbook example taught in Econ 101, and if the "free market" can't even solve even this sort of basic problem without a serf class of undocumented immigrants, it would imply that American-style capitalism itself is a failed experiment.
