The ultimate solution to the scams is to give out basic information in schools. If you don't want to fall for diet scams, learn nutrition. If you don't want to fall for financial scams, learn about financial markets, if you don't want to fall for educational scams, learn about schools and education. I'd forget about teaching the specifics about current fakes (scams evolve) but giving sound information about the subject.
