I have the disposable income and would still not pay 2k USD for a phone a FWIW. But I spend that on other hobbies (just ordered a programmable power supply and an oscilloscope earlier this week, close to that price when taken together)
It’s of course a guess, I don’t know how else you would read such a large generalization. Most of the HN audience is based in the US, most people here work in software. It’s not a crazy stretch
Blue collar maintenance worker here. I will have a yearly average income much higher than most of my peers because I'll likely die before I can retire and spend it ;)
