As much as I'd love to believe the "work more than 40 hours a week, because SCIENCE!" party line, I have a hard time accepting it, and I think so do most people who hear it (outside of HN, at least). For one thing, it's highly convenient that the standard US work-week happens to be the exact "correct" amount of hours to work to maximize productivity.

40 hours is essentially a useful measuring stick and the accepted standard.
Now I do agree that for some people they can and do work long hours and greatly enjoy this and good luck to them. I have to assume they are working at a company where they do work they love and are proud of. I think of employees at SpaceX, Tesla, video game companies for gamer type developers and NASA.
I interviewed at a large game developer a long time ago and was asked back for a second interview. After I discovered they regularly worked past 7:30 at night I declined. I do not play video games so for me the draw was not there but I could absolutely understand how that could be someones passion and they love what they do.
For me I value my family time and when comparing jobs prefer to compare apples to apples and the main way barring a very unique work place is to compare dollars earned per hour worked (including benefits).
To your point though if someone wants to be there, they are making an informed choice and they believe it is an amazing opportunity then more power to them.
