'Nothing good' happens by 'self-oriented individuals doing the least', in fact I would go further and say 'almost nothing' happens at all.
If you've ever been on a 'decent team' you'll see that there are many 'in between' elements of an operating situation that have to be accommodated, and it takes a bit of extra focus and goodwill by everyone if it's going to work out.
This applies not only to tight-knit groups, but large teams, and also to contractors, and can be extended to the system overall, aka companies working with each other, individuals, public servants etc.
We generally have to keep our chins up, and 'try to do our jobs as we can' not the 'minimum we can get away with', knowing full well that it's not going to work out all the time, that some situations are better than others, and that there will be a lot of variables for which your 'expected bonus of 4%' or whatever is only one small part.
This doesn't mean we 'die on a hill for someone else's cause' or work ourselves in a grind for no reason, nor does it mean accepting negative behaviour on the part of employers, and definitely 'some days are better than others' - but 'life is long' and 'consistency over time' does matter.
It doesn't even mean fake emotional posture (you know those people who are always in a good mood!), but rather just 'doing it'.
In most corporate situations, the bar for 'minimum' is actually fairly low and so pragmatically, if we want to be 'trusted' as individuals, there has to be a general expectation that we will do 'it' not the 'minimum' or it just won't work.
Obviously, things will be uneven in so many ways - some people's 'minimum' will be better than other's 'best effort', but that's life - that's all part of it.
It's an issue of productivity, but arguably, morality as well.
It's actually a bit troubling that people would even need to ask the question, I hope this level of selfish orientation is a niche mentality and not some kind of new, secular social trend.
It's also hard to even grasp that people could be so cynical - I feel sorry for people in that posture, because either they've literally never 'been on a team' and have no internalization of those dynamics, or a are just depressed or have a negative life outlook. I'm not very athletic myself, but over the years I've gravitated towards people who do play sports, especially team sports, as having more of an innate sense for those things. Even 'toxic' people are more often than not just misfits, at least they are interesting.
It's a sad kind of organizational problem as well - the people who are overtly bad or toxic are easy to let go of, but the pernicious malignancy of 'do the least' is worse.
'Doing the thing' it usually doesn't cost any more material time, just focus. If you're going to do it, then do it.
