For someone who doesn't want to spend their lives doing stupid shit like cocaine fueled parties and megayachts, at 100k USD (currently) buys you one life-changing event - basic lifelong security, you probably won't have to worry in the long run. At about 300k (currently) you can buy into a level of security that is probably resistant to major worldwide economic or political catastrophe.

If you want to change the world, say by doing an ethical capitalistic startup or meaningful nonprofit, you probably want to start with $5M all-in assets, it's unlikely to be easy to get there quickly on a 300k salary at a FAANG. You will want to roll the dice at startups paying you back in the 100k-150k range.
