It's going to hurt these companies. There is a special vibe when your workplace is entirely staffed by people who hate their lives. It is not an environment conducive to creativity or dedication. Long hours don't make you more productive.

When I think my employer is mistreating me, I drag my feet, I engage in malicious compliance, I always decline to make the extra effort. If I see a problem somewhere that needs to be reported, actually no I didn't. I'm the opposite when I feel rested, respected, and autonomous.

What I think is funny is that Japan's GDP per capita is less than half of that of the US, and Japanese productivity per work hour is also less than half of the US. In other words, Japanese business culture is all smoke and mirrors- it's everyone performing for each other to appear to be working harder than everyone else but they're actually less effective at generating economic growth than countries that don't have this kind of work culture. This shit doesn't work- we have data showing it doesn't. Bosses like it because they're obsessed with the appearance of productivity rather than the real thing because in spite of what all the data says, it feels like having half the workers work double the amount of time will let you get the same amount of stuff done even when that isn't what the data says.
