I don't think the changes you propose can be achieved in the school system that we have today.
Neither do I. Yet I am not the one enamored and fixated on this current system. That is our governments and a lot of the population. It is far easier to stick with what they know than to take the difficult path and get rid of it and replace it. Sadly people will usually take the easy path even if it isn't working.
My previous post was basically about that. Yet I was asked How I would do it... so I wrote this post in response to that question.
