Many teachers in technical fields earn MUCH more during summer breaks. But youre right that the majority of teachers with soft degrees are not qualified to earn their salaries in the private sector.
All those job complaints you listed exist in blue and white collar private industry to varying degrees poor benefits, need to keep up with technology on your own time, no break time at work, after hour expectations, etc.. Sometimes theyre better, sometimes worse, but nowhere outside of teaching is a salary spread out over 2-3 contiguous months where the worker is not working. Theres no way around that. If Teachers salaries are calculated hourly and compared to other professions, they need to be adjusted to account for summer breaks.

Just like a retail manager at Christmas time.
