The school system in America isn't getting better it's just becoming more and more kafkaesque over time. It's amazing anyone manages to eke out a real education out of the system as it is.
Once they have done this, and therefore are completely entitled, they take out their entitlement anxieties on everyone else who was smart enough to learn what they needed to and didnt give a shit about social conformity or status entitlement.
Their collective anger at themselves is what creates homelessness.
