Obviously the parents you deal with are morons who won't raise their little shits properly, that's not in question at all, but your comment comes across as "I hate your response because it's offensive, but also because it's accurate". Was it ever in doubt? Teaching has been deliberately underfunded into being an objectively terrible career path, you get treated like shit and paid like it too. The only people who will do that job now are:

1. Incompetent morons who are willing to work for peanuts after being fired from half a dozen hospitality industry jobs, because school districts will hire anyone with a pulse who's willing to take abuse (Indiana will let you teach with a fucking Business degree now, cosmetology certifications for teaching math can't be far away)
2. Sociopathic sadists who just want to be bullies but aren't willing to be correctional officers
3. Miserable, jaded cynics who don't care at all and phone it in every day
4. Idealistic lifers who actually believe in idealistically Helping The Children, 100% of whom will be beaten down into becoming number 3 within 10 years, except for the ones who quit for a job where they'll make more money and get treated better, such as waiting tables or driving a forklift

Is it any surprise I trashed the teacher in the OP? If anything I was being charitable in assuming incompetence, since we're rapidly approaching the point where malicious conduct will be statistically the most likely and will have to be assumed. Some MAGA-infested districts are already there.
