Earlier quoted context omitted.
To be fair, education in the US is very broken.
It remains unlooted so far. It needs a layer of opaque billing, routinely bankrupting its customers, and profit extraction to match the healthcare industry.
On the contrary, public employee unions (including teachers) have done a masterful job of enriching themselves at public expense. E.g. Oregon:
Member accounts saw appreciable and consistent growth during this time, but underlying pension assets did not grow to cover the increased benefit guarantee. Career public employees who worked from 1970 to 2000 often were entitled to retirement income replacement rates over 130% of their pre-retirement earnings.[1]
Show me private sector pensions (if you can still find any) that come close to that.
