Don't really have taxes at that income level. In the US, ACA pays full insurancne premium (currently, that will change if the billionaire tax cut passes), and 'wellness checkups' are $0 out-of-pocket by law. Most of my dinner recipes are around $2.50/serving at 900 calories. I'm able to walk most places I go, but car insurance is $100/month. Don't feel like dating, raising kids, or making big vacations. I average something around $7-800/month on 'entertainment' like video games & hobby materials, which leaves $300-400 savings. $350/month is 10%, which is around 2x the US average savings rate (https://fred.stlouisfed.org/series/PSAVERT). Savings for emergencies like insurance deductible and for retirement.

But that's my point: my housing probably isn't everyone's idea of 'comfortable,' my diet is pretty carb-heavy and probably not everyone's idea of 'comfortable.' I like it, though. It feels comfortable to me; I don't consciously restrict any of my spending - all the numbers I've given you are post hoc analysis. I've been doing it for a decade.

I don't dispute people feeling like they need $150k to live comfortably. Lots of people want kids. Lots of people want to take a nice vacation time-to-time. There's a massive propaganda machine out there trying to convince everyone that they need just a little more than they have right now to feel good about themselves, and I believe that propaganda starts wearing thin by the time you get to $150k, $200k. They've got to live their life; I can only live mine.
