Or we have laws because a few grifters were so evil and were able to take advantage of the altruism of the majority so badly that we needed rules. The people had to be protected from themselves. If everyone was evil, they would all be so bent on conning each other that it wouldn’t be profitable in the first place. I will say that it seems like a lot more grifters have shown up recently. That might correlate to desperation, lead poisoning, or microplostics though.
