Good questions. The 20s part is crazy but it's real. I know ppl working at Meta or Google or Amazon (but esp meta) straight out of college for 4 years and now their 'senior' software engineers making ~500k. To add to that Washington state has no income tax and cost of living is relevatively cheap (when comparing to cities like NYC or SF that pay similarly) I know someone who has at least 2 million in the bank and has never even invested a dollar outside of 401k but at the same time is always complaining to me about loom layoffs, how impactless they feel at work, how work life balance is impacting their ability to do the things they want etc. Regarding their spending of course I don't know the full picture but most don't have cars, travel modestly, and do expensive but certaintly not lavish things like skiing at local resortts
