ShaunC writes: Is there a glut of qualified American tech workers, or isn't there? Some companies like Facebook and Airbnb are now actively courting and recruiting high school students as young as 13 with promises of huge stipends and salaries. As one student put it, "It's kind of insane that you can make more than the U.S. average income in a summer." Another who attended a Facebook-sponsored trip said he'd "forego college for a full-time job" if it were offered. Is Silicon Valley taking advantage of naive young workers?
