Read my post way more carefully, especially the beginning. I carefully structured it to avoid the "singularly".

Responsible? Yes, along with all kinds of other entites. But all that isn't terribly relevant to my actual point, which is that the political capital that will be expended on maintaining those benefits will create openings to oppose the teacher's unions in other ways.

If you want names named, the SEIU is the biggest problem of the bunch. But it's all the same problem, unfunded defined-benefit mandates. It doesn't matter who is getting them when they exceed what society can afford.
