The ability of students to get jobs drastically depends on what they're studying. In my years as an engineer I worked with a lot of technicians and a lot of them were trained at "for profit" 2-year colleges. But even the 2-year colleges that have a long history of feeding industry (like ITT which started out as the training division of International Telephone and Telegraph) have tended to add fluff degrees.
The reason students go to these schools is partly that some of them have very good records for placing students in industry. A typical student is already employed and needs the flexibility. And the for profit schools are generally better at keeping students enrolled. For example, some of them expect their instructors to call up students who do not show up for class. This doesn't happen in the government schools. And the for profits usually have better facilities, at least according to my observation.
But I wouldn't touch any educational industry investments right now. We're in a massive education bubble with the public getting way too much education at way too high a price. To fix that, two things have to happen. Fewer people need to go to school, and the amount they pay for school has to drop. That's not the recipe for an expanding industry.
Hey, things like "nursing homes" are a good growth area.
