I'm in agreement with Diane Ravitch, the historian of education, that the college education major should be abolished. Instead students who aspire to be teachers should get a degree in any other field, and take a few courses on classroom management.
Teachers dedicate themselves to teaching for numerous reasons. They don't take on student loans for no reason whatsoever; the credentials they get are part of the price of going into a system with intentional barriers to entry.
Don't confuse a system of "reject some of the good, weed out most of the really bad, and usually get ok results" as something which is an entirely accurate indicator of competence. The shortcomings of the current system don't make it a lie, obviously - but putting decades into a process doesn't necessarily make it better, either.
I'm saying that in many cases, if suffices for a parent to simply understand what subject materials their children need to learn, and then teach them to read well at an early age, after that parents do not necessarily need to be knowledgeable about those materials because the books contain the knowledge.
I think what I'm describing is nearly synonymous with the hacker mentality that I would expect to be held in high regard in this forum.
