That's because risk-aversion and laziness are the smart things to do. Yes, it would be cool to come up with the next Facebook, but most financial advisors will tell you that the actually best thing you can do is some form of "SP500 and hold 20 years" because from the perspective of an individual, the safe option provides the best expected outcome.

Similarly, why work yourself to the bone for a miniscule chance of success, if you can... just chill instead? I used to be a highly-motivated go-getter, but then I realized, this shit ain't bringing happiness, and I turned into a work-avoider who spends time in the office mostly talking to coworkers and playing games in the toilet. My overall life satisfaction skyrocketed.

Yes, the society at large does need people to do the needful, but this ain't gonna be me.
