I think the takeaway, in light of similar articles over the past year, is that nobody knows, yet. It'll take more time (maybe even another year or two) for all the numbers to come in and various patterns--in particular their magnitude relative to each other--confidently identified. I could hazard some educated guesses, as I'm sure you could as well, and we'd probably be right, but it's probably better if we just abstained from too much speculation. It's not like pinpointing the exact causes is going to help those public school districts already in dire financial straits; certainly not in the short-term, at least.
