The answer of course to the comments above regarding hours for instructors is to leave the requirement low, maybe a bit more than now and enforce very strict supervision requirements. Trouble is that many present CFIs have not been trained to that level (because they grew up in the existing system, which I think we agree is below par) nor perhaps have the resources to do it. Now what did I say about limiting the number of CPL schools... then maybe it could be done?
Standards and standardization is what we want. With few exceptions it does not exist right now!
