As people have indicated it just depends on where you are willing to live. Michigan is one of the best paying states in the nation, especially when you compare cost of living. You can easily find information online since teaching is a public job, unless you want to also consider private schools. Private schools generally pay less.
I think southern states generally would drive you crazy, except for specific cities where the population is more liberal, and of course southeast FL is a huge exception to the southern rule, being full of northern transpalnts. Also southern states generally pay much less, but that varies, pay scales will be on the websites. Having said all of that I am living in the south, and it’s not all bad of course, but it is not the perfect fit for me.
Some states are much easier about their requirements. Many times you can have a degree in almost anything and teach high school, not sure about primary school, primary might have more requirements? Anyway, many states you can have a degree and while teaching pursue credits in teaching to work towards a certificate, and whatever other requirements there might be. Each state is different. Public schools are generally governed by local government not federal.
