> Many teachers give their lives to their students and work 24/7.
I find this more true for the (way) older generation, either because of the harder times they grew up, or maybe just because of natural selection and only great teachers stayed in profession that long. Among younger ones, I see (often, not all of course) more pragmatic interests – feed the family, spend reasonable time/effort, this is the only job she is qualified to do… This may be in part as the only challenges of latest generations were such (pre-covid) or maybe, it is just a phase and they’ll grow up, I don’t know.
