Of course it's harder to educate and socialize kids in our schools. Education and socialization begins in the home with the parents, as the article points out. Progressivism has destroyed the family with both parents out chasing the buck and no one home. Then mommy is too tired after a hard day's work herself.
Wait, isn't that what public school is for according to the progs in this forum—socializing the child? Can't have it both ways.
But I don't think it's just teachers that are tired—there's other professions too. How about when ambulances line up on 5th Avenue in NY to pick up collapsed art directors in a top design firm after annual report season? Yup! I was told that at a job interview at that very same place. It's a burn out profession too.
