Why not? I am not a teacher (although my sister is). Why shouldn't we pay our educators to educate our children? What price tag or value do you put on the education of your children? We pay athletes millions of dollars a year but we don't want to pay our educators?
I think people worry so much about how much teachers earn because they have this belief that because they pay taxes, and taxes are used to pay the teachers, then they are paying the teachers and should get to control how much the teachers get. They think they are the teachers' bosses. Of course it doesn't really work that way. If you think you should be able to completely control how much the person who teaches your kid earns, you should hire a tutor.
Obviously teachers earn a decent amount in some areas. Both of my inlaws taught until last year and together they didn't earn as much as some teachers mentioned on this thread, so it clearly varies quite a bit from one area to the next.
So many people have the perception that it's "just" teaching, so teachers shouldn't earn much. It isn't important like being a football player or executive. After all, anyone can teach.

I think most of the people who feel that way have never taught. It does take some special skills to be a good teacher. I'd really love to see some of the teacher bashers spend a year in the classroom, dealing not only with the kids but also the parents and the ridiculous policies that teachers are forced to follow. Oh yeah, and the budgets, when you're expected to do all sorts of things in the classroom but you don't actually have the budget to pay for any of it.
I don't complain about how much teachers earn. But I do have to object when people start trotting out the numbers as a justification for their expectation that teachers should put in even more hours. "Working" parents (as though teachers - or even stay at home parents - don't work) seem to think that teachers have all this "free time" and they ought to be willing to donate their time to make the parents' lives easier. Teachers already work full time jobs. Unlike those in most professional careers, they don't have much chance to earn promotion and raises. My husband works crazy hours but he sees that pay off every year when he gets his yearly evaluation. There's an incentive for him to work longer hours, to show that he's deserving of that next promotion. People always mention that sort of thing. They carry on about all the unpaid hours they are expected to put in to their job, and seem to think teachers should have to do the same thing. But they have a reason to do so. What incentive is there for teachers to devote all their time to their job? Most teachers put in quite a bit more than the minimum they are required to do, but there's no real benefit to working the extra time. They aren't going to get larger raises or bigger promotions than the teacher who does put in the minimum. They're doing the extra work because they think it's the right thing to do, but some parents still expect more. Because the parents have "real" jobs, they think their time is more valuable than that of someone who is "just" a teacher. I really think some people view teachers as nothing more than some combination of indentured servant and glorified babysitter.
