>>>We also have enough fast food workers. That doesn't mean they're doing the job because they want "a satisfying job with good benefits." That's definitely not a good assumption about any profession.
Teaching (in US/Canada at least) requires at least a bachelor's degree and some specific teaching training. It's reasonable to think people aren't forced into it due to inexperience/low skill the same way fast food workers are. They must have some reason for choosing to be teachers - and you're right, I was making an assumption based on the people I know personally, which may not extend to the whole population. But for whatever reason, lots and lots of people, armed with the knowledge of what the wage is, are choosing to be teachers. Indeed, in some areas in my province we have a glut of teachers applying for a few openings.
>>>it's a vitally important role in our world's future. I for one would not call "supply and demand" at the lowest possible rate a good way to treat such a profession.
What is the appropriate way to decide pay? We have a spectrum of possible wages we could set, from the lowest amount possible to ensure enough adequate teachers to the highest amount we could possibly afford (assuming teachers are public employees, this is related to how much we're willing to pay in taxes). Where should we land on that scale and why?
