Do you just actively dislike teachers?
I think teachers are great. They do a job that I simply could not do. It's not for lack of education or ability, but a lack of patience. I'd lose my mind in the first week--probably the first half day.
That said, I think our educational system has been captured by the teachers union, leading to a system that isn't particularly good for good teachers, and isn't particularly good for students.
We simply have not made any meaningful effort to measure teacher ability and effectiveness. Standardized tests isn't it, because too often in a lot of schools it's garbage in, garbage out. If you get a class of dullards in September, they're not going to be brilliant in May, no matter how good of a teacher you are. So teachers [understandably] don't want to be rated on the failures of teachers from previous grades. And to an extent, you then get to a "teaching to the test" mentality rather than trying to actually give students meaningful information and skills.
Since we don't have meaningful measures of effectiveness, then, the teachers unions tends to reward seniority, credentialism, and checking boxes like "continuing education". It doesn't matter if a teacher is coasting through 20 years of burnout, if they've got the seniority and have been checking those boxes for the past 20 years they'll have better salary, priority in the event of and staff reductions, than the 28-year-old bright eyed teacher that connects with students and makes them excited to show up and class and learn.
Ideally we'd love to see something like sports WAR as a metric for teachers' effectiveness, wins above replacement. But we don't have anything like that, and the teachers union doesn't want it.
Calling out problems in the system, a system that protects ineffective teachers and does little to reward the truly outstanding teachers, isn't a dislike of teachers.
