Psyche profiles. People are periodically given psychological evaluations to determine the likelihood of sociopaths or psychopaths emerging and then giving them a rigorous course of ethics training. After that, make the consequences for ethically bankrupt behavior severe.

Data science is already being used to psychologically profile consumers to determine how best to get the most greenback blood from the meager stone that is lower middle class America. Turning that paradigm around so that it affirms basic dignity and ensures an equitable society is one of the only options I see for the future.
