Teacher health insurance is an absolute disaster. The greater problem is health care costs in the US. If you're young and healthy, you can look at a less costly plan, but that's betting that you won't have any kind of health catastrophe. You could also go out on the public health insurance markets and get a quote, maybe there's something better for you out there. If your wife works, maybe there's something better there. Sometimes it's worth it to have you on your insurance and her on her own.
In most other white-collar, college-educated careers, employers pay a much larger share of health insurance costs. That's unfortunately not true of teaching. For those whose spouse is working a better job and has insurance, it's no big deal. If you're counting on that insurance, you're pretty well stuck.
Wouldn't it be nice if health insurance wasn't tied to your job? It's a ridiculous system we have.
Long-term, vote for people who will do something about health care costs. Or you can vote for someone who will cut your taxes. Usually those are not the same candidate. If there's a candidate promising both, I'd like to see their plan for how to accomplish that.
