Joe of course will be greatly missed, and was an old school legend of which there are sadly very few left.
Speaking of schools, maybe it would be kinder to say it was a much better fit for the more prosperous late 20th century than for our modern era's economically troubled times.
I went to university practically for free, paying mainly for a few used textbooks (only 15 bucks or less a pop), but that was easy to do back in the good old days. Same thing back then with trade schools (where a couple hundreds bucks used to get you a fairly long way).
But after Reaganomics hit, it became a far different and much more difficult world. So it's really not fair to judge setups like the Kubert School in view of today's crazy downturn levels, since such institutions had their last best chance at significant success many years ago.
