I wonder if you have ever challenged a crap school owner and tried to close down his/her school, or tried to publicly humiliate that person and ruin the reputation of the school. I am willing to bet that you have not.

You're right. I have not, because I have not had to bother. I have been lucky and smart enough to choose schools which work effectively. I have managed to get changes made in some small, but significant ways, and without raising my voice.
