Luckily, most things that make adults happy need money to support, and this sustains the driving force of human society's progress.
Yes, whether or not it's acknowledged, the most primitive driving force that continually pushes human civilization forward is still human desire, especially greed.

Then, by setting legal boundaries for greed, the embryonic form of the entire human society is constructed.
