This is a assumption I have about most folks who are engaged enough to be on hackernews (I guess US based). With the possible exception of those folks who live in HCOL areas - most software engineers I know have a comfortable enough salary to remove obstacles to happiness. Many do choose to prioritize money over other factors - but I often see it used for more hedonistic/luxury purposes - which IMO isn't really conducive to long-term happiness.
Time is our most valuable resource - 40 hours a week is often more time than people spend with their families and friends during the week, so making sure that that time isn't just a means to an end is something I've tried to prioritize in my life
There are a whole lot of working class people working in low paying jobs like social work because it aligns with their values.
It's not a given that people only prioritize their values after they are financially comfortable. It does seem to be the case that many people in the software field do.
