This is the endgame of rent-seeking and an abundance of (concentrated) capital, in a country that is largely comfortable letting everyone fend for themselves. Who needs to build cars when you can tickle Sam Altman's Markov chain generator for $45,000 a month? I mean, I don't blame anyone, and I need money as much as the next husk of a man, but I really wish hustle culture would stop permeating every last open space of our lives. I'm depressed about it, too, and I don't see it getting better any time soon.
Which country are you referring to? You will find a lot of hope if you study a little history and see how this has always been the case. I would guess that in terms of rent seeking and of hustle and useless products things are improving and much better than they used to be. It’s too easy to forget the vast array of useless and even harmful crap people have been selling for centuries if you didn’t live through it and/or don’t know about it. How many civilizations in history had despotic kings that controlled all housing and income, and nobody was allowed to earn their own money? The existence of someone making a decent living on products you don’t appreciate isn’t evidence of rent seeking, it’s evidence that we have more freedom than ever before, and that people have a wide range of tastes and the ability to spend a few bucks on little things they enjoy or save them small amounts of time, no?
What a weird take, as if someone building cars is prevented by them also selling supposed pet rocks online. Lots of people, Musk included, made enough money from throwaway startups to then work on the bigger problems, as they're actually financially secure to do so at that point, the Maslow's hiararchy of needs in action. If you don't like someone's product, don't buy it, but if other people find them useful, good for them and good for the creator.
Edit: clerical error.
Edit 2: added despair.
