Iâ(TM)m in what is probably my last decade or so of a highly technical career in industry since getting a PhD. Would be tempted to forgo the remaining income and teach high school, college, or grad levels, if I could figure out how to do it while avoiding the incredible amount of overhead bullshit that comes with public schools and university administrations. Iâ(TM)d teach for free, but you couldnâ(TM)t pay me enough to deal with that stuff.
My opinion is informed by observing family members teach over the years at secondary, collegiate, and grad levels.
