Also, lol at someone in tyool 2012 pretending that there are still jobs that require no education. Even understanding the marketing plan for a chain retailer requires more literacy than most people get from high school. If you want to solve what you see as a market failure (the waste of resources on unnecessary education) you probably shouldn't start your idea with a snipe hunt.
Edit: also, a degree is pretty obviously a Nash equilibrium, so unless your plan involves making it illegal for degree holders to work certain kinds of jobs there is literally nothing you can do to change this situation. If you add a new certificate between an associates degree and a high school diploma, you're just making another new thing that a high school graduate needs to get in order to assemble sandwiches. gg.
