i'll describe the lifestyle you probably can't afford - $20k vacations, $500 dinners, $100k cars, and $1M houses. not appetizers and taxi rides. appetizers and taxi rides are normal things that normal people buy. even normal people who don't have a successful exit under their belt and don't have a successful new business as an investor.
this irrational overemphasis on frugality i always see on hn just seems like a different form of elitism / pedantry to me. since most of us have money, it's just a covert way of signaling an extra level of self-control and discipline (which are usually required to make money, but since so many of us make money, we've got to find novel ways to signal that extra status).
