I didn't use the word "jealous." I think that's true in many cases, sure. But I think about 70% of the people who hate Musk have never felt jealous of him, either.
Do you think people should be allowed to be billionaires? Did you know that many of the haters don't think they should? They are fundamentally opposed to the idea of people being exceedingly rich while others are poor. If that's you, maybe it's influencing your opinions on why people hate billionaires.
I don't think I have blinders, but it's hard for me to evaluate since you made that ad hominem attack without including any details. I'm not a Musk fanboy, or an all-billionaires fanboy, I'm an internet-hater-hater. I think you (and journalists) have about as much chance at predicting the outcome of Twitter as chatGPT does.
