You are making 3x the median family income for this country while getting to work from home and stay safe from COVID-19. The job market is imploding around us while we work cushy tech jobs. Abject misery abounds as people lose their loved ones and their livelihoods.
It comes off as as quite tone-deaf when tech people complain about their $150k salaries. There are way too many entitled people in tech who have never worked a shit minimum wage job in their lives.
Look, if you really want to make it to a company like Jane Street, there IS a path. It's not a path that many have the energy to take but it's there. If you are having trouble getting interviews you can do a ton to produce content needed to raise your online profile. You can make lots of meaningful open-source contributions on github. You can produce great blog content. You can code live on twitch and develop a following. If you combine that with actually developing the algorithmic chops to pass their interview process, you can get into a company like Jane Street.
I personally don't view maximizing my income at the expense of all else in my life as a good way to live so I won't be grinding it out to get one of these jobs, but if that's what you really want then the path is there. But you probably will still be unhappy once you achieve it if you're unhappy right now.
And don't be so hard on yourself. If you've made it as far as you have, you definitely have successful characteristics. You're not special, and that's OK. But just because you're not special doesn't mean you don't have successful characteristics.
