One should note that from the nineties onwards we put a large portion of our kids' education on the stock exchange and in the hands of upper class freaks instead of experts.
That is true. And I do not argue that education cannot be better and more fair. We saw how train privatization worked for Sweden. Education should not follow the same path.
But I have seen too many people arguing that education is collapsing and privatization is the answer. It is not. Improving the current system and removing private schools is the actual solution.
