Japan has a culture of running trains on time though. There is no MBA figuring out that they can pay themselves a bigger bonus by firing the backup train drivers needed to ensure on-time service.
And even if there was they couldn't thanks to unions and some of the strongest worker protections in the developed world. That doesn't even touch on the loss of face for proposing such a thing.
Is it really their recipe for greatness? We have very strong unions and worker protections in France, and our trains are unreliable as fuck. I'd be more inclined to think that their highly developed feelings of pride and shame are bigger drivers.
Spoken to a few ojiisans here over the years and they'll always mention the value placed in making sure everything's well maintained. If you go out past midnight in Tokyo you'll frequently see gangs of workers on the lines doing inspections and installing new equipment. Can't comment on other countries but if you're not doing enough upkeep things will turn to shit fast.
