one thing that I found works: religion. ask the engineer about to enter the arena what they would like to do with the money they hope to achieve, their end-goals, etc. then follow-up with whether they would feel morally/spiritually at peace with their choices and methods after the fact (do your ends justify your means?) in my experience, the people with the IQ to earn a yacht responsibly end up settling for a speedboat anyway.
