For root causes, the morale environment is largely politically induced in a coordinated attack on public education that goes back to the 80's. For some examples...
* cuts on school lunches https://en.wikipedia.org/wiki/Ketchup_as_a_vegetable
* voucher programs https://en.wikipedia.org/wiki/School_voucher
