You say you're getting richer. I'm getting poorer.
Want to give me some money to balance things out?
Probably not.
The rich don't care about the outcome for the rest of us. They're building bunkers. You should do the same if you can. Sam Altman, or Sama, as people affectionately call him, has guns, anti-biotics, etc. stockpiled in a remote bunker where he can survive the collapse of society.
Also from the sounds of it, and the fact you are both on HN and doing well in the market right now, implies you are in a pretty good position, compared to the general population.
To answer your question more directly, the market is doing well because both the metrics and mechanics of markets are heavily heavily gamed. The 1 trillion dollars that is being added to the US debt is going _somewhere_. You happen to be getting a piece of it which you think is great (understandably), but you can be assured that there are many people above you in the chain getting much bigger pieces, and people lower in the chain getting less and less.
A dog hanging around the table of warlords will be a lot better fed than the dogs whos owners just got their harvest taken from them.
This bothers a lot of people but it doesn't bother me. I see it so often that it feels like a flamebait tactic to elicit envy.
It seems like you weren't really asking an objective question of 'why this is happening' but rather a subjective one of 'why should I care, I'm doing fine'
It's a valid question, why should you care, if you are doing well in this moment. I can't answer it for you.
The second one answers the first.
You can't have both - either you're part of a community, or you're on your own.
