Well, tell me a physical job where I can earn 150,000 at least? (which is not so much for mentality)

The sanitary technician is not the drunken uncle Vasya of ZEK who cleansed your damned toilet, but the one who works for himself.
A caretaker who does repairs in apartments and houses.
The highest class.
But you, school, are far from these people, however, as well as those who earn 150k mental work.
