It's also culture. The only place I hear about crunch mode is Hacker News (e.g. Silicon Valley) and game programmers. I'm in Europe.

In fact, we have the opposite problem: a commonplace deeply-felt entitlement to a decent salary for max 8 hours a day, by the clock, never more, but also never less. This prevents crunch mode to happen most of the time (fortunately), but there's plenty other problems instead, such as a lack of commitment and team spirit, people who don't care about outcomes but just about clocking their hours. Stuff like that.
