Why rank it like that when there is a complicated set of variables, not limited to cost of living in SC vs other states. Instead of ranking them per state, which is just a way to escalate teacher pay in perpetuity (after all, if you're ranking them like that, someone will always be 50th, and that's "unacceptable"). So could the state do better in teacher pay? Probably. We need to evaluate teacher pay based on median household income vs median cost of living rather than "other states pay their teachers more than ours!". I'm not arguing against your point, just that metric. It's a terrible metric.
Well we can disagree on the metric while agreeing it sucks. When I graduated from USC in 2001, a teacher with a Bachelors Degree in Aiken County was making $18,500. I could’ve worked at McDonalds and made that.
For 3 of my 15 years there has been no pay increase. For several others the increase did not match the increase in insurance and cost of living. I actually get less dollars when you account for inflation in 2020 then I did in 2004.
