I have found that many of the affluent engineers that I know exhibit this sort of... line of thinking. this how should I say, false frugality, that at the end of the day doesn't really move the needle much (since they're making 200-300+K TC minimum) but makes them feel good people who will, instead of directly using their subsidized subsidized clipper card benefits, will load their clipper card with credit cards for the 2% cash back, and then manually submit an expense, creating an operational burden for their company finance team so that they personally can read the benefits of... $25 a year in cash back people who will take UberPool/Lyft Line to save 4-5 dollars for their commute home at the expense of an extra 20/30 minutes instead of either a) just taking public transit or b) taking a regular uber people who will buy take out containers and bring them to work to take company-provided catered food so that they can save $20 a day people who will use credit cards to buy gift cards at grocery stores for 5% cash back (obviously if you buy a $1000 gift card for $50 cash back, that's great but you run the risk of either losing the card/and thus losing cash/losing the credit card purchase/price matching benefits/etc etc) all in all I think regardless of income/net worth sometimes it's not about the money. they can afford it. but it just feels good to save a little bit of money relative to your net worth way more than the actual financial impact
