n economy we are told, simplistically, that humans maximize their wealth and then gain happiness by spending their wealth for consumption.

I think I want a closer model that can also extend to political realm. Humans want power. They will use their power to gain happiness. Happiness are often obtained by unhappiness of others, usually the very rich.

For example. Say I want to explain why drug is illegal. Using theory #1 it doesn’t make sense. Even if it were true that drug is dangerous, why in the earth people would go the extra mile protecting others from self inflicted danger? It presupposes that society love you more than you love your self, which is a great over estimation of society’s love by a factor of 1000. However, theory #2 fit perfectly.
