Not having a graduate degree hardly means you're undereducated.
True, but MANY Middle and High school teaching positions require a Masters. Despite a severe shortage of 'STEM' teachers, districts have not relaxed this requirement and would be unlikely to do so even under the proposed tax bill.
Ah, I was not aware of that. That's especially problematic given how low teacher salaries tend to be.
They make up for it with good healthcare, pensions, and unions. You may not make much, but you'l make it to retirement. Hence the push-back against charter schools which have none, essentially.
