The only reason people make money off of stocks is because at the end, someone gives those companies money. And everyone has a choice to vote with their wallets and through their actions in general.
For example, take Elon and his actions over the past few years. What should have happened is that Tesla sales dropped across the board, and everyone who owns a Tesla should have been in a rush to sell it for fear of it getting scratched or them personally blacklisted from stuff and ridiculed for driving a Tesla. Tesla employees should also have faced the same public pressure and quit.
But people don't care - at the end of the day, politics on Capitol hill is mostly a meme, but what matters is their personal satisfaction. And you look ridiculous if you refuse to get in your coworkers Tesla. So now Elon is a trillionaire.
On the flip side, in a capitalistic sense, it honestly doesn't matter if people are rich, the thing that should matter is what power the money gives them. Rich people buying mansions is a good thing - thats money to workers for construction, staff for housekeeping, and so on. Rich people doing things like being able to buy whole media platforms and censoring things is definitely not good though.
The question is, is society headed in a direction where people have more and more apathy and eventually nothing will matter as things get progressively worse and everyone is just complacent, or is there a bottom line where people start paying attention enough and actually fighting for change when it gets bad enough.
