"The default for a parent is rather to imitate their peers and outsource the big decisions to bureaucracies."
No, dude, parents often have to go to work and don't have the means to hire a private tutor. Most don't have a grandparent around neither.
One colleague was arguing that the standard school system was very destructive to children and alternative schools were doing a much better job making them able to think. However, she also said she is sending her children to a standard school because of the cost and complexity. In other conversations, she mentioned that her neighbor complained about the noise of their private pool cleaning system, which is still an ongoing problem, or how going skydiving was a great experience.
There is a lack of self awareness in how "doing like normal people do" is influential to most people. People work for shit they don't need, and don't really think what is going to bring them happiness.
What do you even think "people like you" is? I would return the question but you seem to have already answered that in the 'about' of your profile.
