For many people, homeschooling isn’t an option.
I know a few teachers. They have quite a range of political views. No one writes a news story that says teacher taught his/her subject then went home. Many teachers are decent people.
“Many teachers are decent people.”
Many Nazi and Commie functionaries were “decent people” - but they did very evil things while at work.
Same for teachers, in that they know the students are unprepared, can’t (and all too often “won’t” learn) and yet they take a check for a job they know can’t be successfully done.
Lawyers have names for such behavior: “improper enrichment”, “fraud”, etc.
To put it more bluntly, most of them should never be allowed contact with any children. I thank God I never had children because I would be the kind of parent you read about that ends up being arrested due to interaction with a teacher.
