I'm glad to have a couple of people comment on why they think the age thing is a problem. I think I'm going to stick with my belief that there is no problem. It still seems to me like much ado about nothing. I believe that I understand why Lemonade and J.D. have a problem, I just don't see it as one.
That said, Lemonade, your assumptions about the age of college age students is false. Obviously, the majority of undergrad students fit in the 18-23-ish age range. But not really very close to 95% The reason I'm harping on this a little bit is the fact that I'm completely positive that I would have gotten a better education if I had worked a couple of years before I went to college. I'm not whining about it, but if I'd known then what I know now, I would have waited a little bit. Quite a few kids these days are doing exactly that. (I'm not suggesting that this has anything at all to do with the older hockey players, but since I objected to your use of the phrase college-age kids when it's clear to me that a 26-yr-old absolutely is a normal college-age kid, I reckon I ought to make my point.)
The Hamilton Project works out of the Brookings Institute. Their data comes from NCES. I'm not sharing this because of the data at for-profit colleges. I'm pointing out that according to this, 20% of undergrads at typical colleges are 25 years old or older.
