So, are schools expected to teach kids how to wipe their ass because they might have dumbfuck parents?

Yes. I know so many people who didn't learn basic hygiene cuz their parents were dumbfucks. I was one of them. I didn't know that u have to clean under ur foreskin. When my penis started to stink one day, I learnt about this. Another example is brushing ur teeth. I'm quite sure that u rinse ur mouth immediately after brushing, rinsing the toothpaste away. Did uk u were not supposed to do that? Fluorine in toothpaste requires time to act on ur enamel. Hence, while u should spit the toothpaste out, u shouldn't rinse ur mouth always.

How many cases of dental cavities have occurred due to people not learning about this? Cases which could've easily been prevented by good education.

Are you seriously expecting the school to teach every fucking basic things of life because bad parenting is a thing?

Yes. It isn't the kid's fault for having shitty/no parents. It is however society's fault if the kid has to suffer through the effects of shitty/no parents.

Start paying teacher like you pay doctor, lawyer, dentist or even construction workers and then we'll talk.

So we do agree. Of course teachers are incredibly underpaid. Of course they need to be paid as much as doctors, engineers and so on.
