they are happy to spend money on technology and shiny new buildings.
they aren't spending money on teaching staff. teaching staff who are now more credentialed than ever, but know less than ever.
the issue is the metricization of education. everything must be measured... and this creates a perverse system where everything is now about increasing the metrics, regardless of improving education.
not to mention the changing in parenting where ever parent things their child is a genius and it's the 'school system' that's failing their kid, instead of their kid being a dumbass jerk who refuses to learn or participate in their own education.
