I find it much more enjoyable to be great at many things, have some financial stability due to having an average job in tech than making millions by being C-level on a trashy company like Facebook but unable to do any sort of physical activity and enjoying very little of what nature has to offer, just seeking as much comfort as you can, you can look for adventure. Adventure is just everywhere and is generally free or cheap. It will make you stronger and little by little will make you less worried about those rich people and rather appreciate how life managed to shift you to the most wonderful road one could be, of self-discovery, of finding a bigger truth, of empathy.
I climb, I skate and so on. I read philosophy, I have time to invest on myself on things which won't generate capital for me and I find it very amusing that even with that, I can still have a huge degree of financial freedom, as long as I work 8h a day 5 times a week and a small, but growing investment portifolio.
If you would work at a FAANG, or even be a C-level there or at a startup, there is no way you could be climbing and enjoying things on your 20s or 30s. By the time you would "make it very big", you would already be too old for this kind of things, not really health or body-wise, but you would be too attached to comfort. If you are more adventurous, you would actually look for opportunities that you could sleep on the floor, have some food deprivation and a hard adventure to test your limits. It's much more exciting than going to the office, doing politics and all. We aren't made to work in such artificial environments and that is why you and a lot of people are sad.
For me personally, I enjoy going to work, could be a few less hours and I would be happy with it. Even studying coding is nice. But I also need to go to nature, hug trees, climb mountains, hurt my foot and body whist doing it, accepting the discomfort of life as it is, in order to appreciate it. I would kill myself if all I had to do was to work, take care of kids and have expensive and comfortable travels. The best things in life are free or cheap. A kiss. A laugh. A new route.
Recently with my wife we've decided for ourselves that we don't need a kid and would rather enjoy life. There is a grind in having kids and at least 9 out of 10 friends I have that went this route are unhappy. Why have kids if I am already enjoying my journey?
Therefore, I can't be discouraged or distracted because people are doing so much better as you say, because this isn't better for me. If all you do is work and you aren't making as much as them, I feel sorry for you, maybe you are more like me, a monkey-man, that goes to the office and after work goes climbing. Or do anything else. If to be homo sapiens means to accumulate capital and shoot rockets to space, I don't belong there.
