Just FYI, Not everyone feels jealousy like you're suggesting here.

I know I never have. I never understood why people get so worked up about that sort of thing honestly. It never bothered me if someone wanted to date my ex, or if they had some sudden windfall, or are doing well.

But I see some people feel this intensely! I'm sympathetic, IMO, they don't choose to feel that way. But it's funny to me, if I were to walk down the street and see two people, and give each of them $5, it would be all smiles. But for a certain percentage of people, if I gave the person on the left $5 and the person on the right $100, they'd feel worse than when they had no money!

Never said everyone, but it's definitely prevalent. How prevalent could be an interesting discussion (I don't know the answer) but I have many reasons to believe most people do experience it from time to time based on my personal experience and how I interpret behavior of others. Also there is a biological/evolutionary incentive to be a bit envious and jealous which affirms my conviction that it is prevalent.

Moreover - how do you know you won't experience it in the future? Have you ever been unemployed for 4 years? Maybe being unemployed for 4 years would make you envious of a friend who just got a job in Google. Have you ever been with a woman you loved dearly only to find out she cheated on you and left you for another man? Maybe going through this traumatic experience would make you envious.

I'm just saying it's easy to be content when things are going well, indeed I don't feel much envy - but I'm super aware I am quite lucky. If things stop going well who knows what negative emotions would pop up - it won't be a picnic thats for sure.

This is interesting, I'm the same as you. I can't really explain why, and I don't think that I have higher morals or something like that.

If I played the ultimatum game, and the other person offered me 0$ out of $100, I would let them have their $100.
