The coach is a sociopath. I’ve had several supervisors like this.
I have as well. The difference between the sociopath boss and the government school is that I was free to look for work elsewhere and I did.
Government schooling, though, is in someways like a prison. Unless the parents can ransom the child by way of home or private schooling, the child is under police and court threat to be in the government’s institution ( prison) and under the direction of government school employees ( guards). It is the government employees ( warden and guards) who determine with whom the child will associate ( be imprisoned).
Also...Government schools have a price-fixed monopoly cartel on many sports. They are the **only** avenue to advancement in many sports. In many counties in this nation there are **no** private schools because the private schools can not compete against a government education-industrial complex that is giving a service away for tuition-free.
With this mix of socialist-entitlement and cartel price-fixing, there is far more opportunity for abuse ( and incompetent training) of the child in government sports.
