Note that it isn't the case that anybody who goes into management is automatically survival-oriented as opposed to doing-good-work-oriented. It's just that the ones who prioritise their own survival tend to survive longer than those who do not. It's sort of a combination of the anthropic principle and tragedy of the commons - management is the way it is, because if it weren't, it wouldn't be where it is. Meanwhile, if your company was structured in a way that rewarded striving to produce quality product using humane practises, you will (paradoxically) make less money over the long term than sweatshops. Sadly I'm not smart enough to come up with a system that fixes this, except perhaps to run companies like democracies and do away with monarch-style CEOs. But then my employee-focused democracy would be outperformed by the money-focused kingdom next door.
UBI would help these situations. Those managers would probably invest less time in the survival mode stuff if they knew there was always an option out. Further, their staff wouldn’t need the work so desperately so the amount of stress they felt would be “capped”.
