I’ve done both, and I don’t think the differences are ever ones that will be resolved.
Not every teaching job is the same.
Not every private sector job is equal.
For every private sector employee who is working 10-12 hour days under constant stress and pressure to deliver with very little holiday, there is a teacher of an unruly class(es) of 30+ kids with difficult home lives and difficult or disinterested or aggressive parents who takes their work and worry home with them and probably could have an easier life somewhere else.
For every teacher who has a lovely class in a lovely area and generally sticks neatly to their prescribed hours or less and enjoys long holidays (and yes many DO exist widely no matter your experience), there is a private sector worker pushing some paper around without much to worry about and working a strict 9-5 with an hours lunch.
So it’s not about teaching v corporate, it’s about everything jn between. I know many teachers who would be utterly eaten alive and wouldn’t last five minutes in the corporate world. I also know many people from the corporate world who simply wouldn’t have the resilience and patience needed to get through a year in a tough teaching role.
There are good and hard working people in both sectors. There are also useless and lazy ones in both too. The sooner we all acknowledge that the better imho.
