I'm not saying that parents don't matter, just that teachers _do_ matter. Both play an important role in setting expectations. Someone with bad parents and bad teachers is likely to have a rough start in life. Having good teachers can give children with bad parents a fighting chance.

Of course, in the US many people strongly in parental control, to the point that you need permission slips to discuss simple facts about the human body or climate change. Sometimes these cultural challenges make it difficult to be a good teacher.
