When I read "for profit" institutions I immediately think of ITT Tech and how it came under fire for questionable practices--as may of their students fell under crippling debt.
I think a question we should be asking is whether or not these "for profit"institutions should exist--these institutions' goal is to make revenue and would therefore have little incentive to provide anything else other than the programs they offer. They are however, able to offer flexibility that perhaps a "normal" (non-profit) 2-tear/4-year can't offer (night classes/or online classes) to people who work in the day; there may be some "non-profits" who can also offer this, but it is often at a very limited basis. After doing a quick google search, it seems as though many of these "for profit" schools are focused on trades, offering programs in automotive, nursing, etc.(there is also K-12 "for profit" education"). What would happen if these "for profit" institutions that are backed by private corporations and investors were instead backed by federal/state funding? Of course, that'd be a whole other discussion/debate and possible policy brief--but just a thought! Also it can be argued that even "non-profit" colleges/universities can be seen as "for profit" as they are often run as businesses (offer services, advertisement etc) and there is a reliance on tuition etc. to help pay for facilities, professors, etc. Key factors that differentiate these institutions from the "for-profits" is that they offer a space to create networks/socialize and at times produce knowledge/research that is shared with the world.
