Even in EU Countries shit happens.
But I definitely, very very definitely thank God that I was not born in the US.

I work with Systemic Organizational Development. It's not easy to convince business people of how the healthiness of the relational dynamics in the team is crucial to the long-term success of a Company.
Why should they want to believe it, when the example they have of "successful" businesses are ethical nightmares like Facebook, Twitter, Amazon?
Probably, an important aspect of the talk about 4 weeks is the definition of 'successful' business.

Well, we live in a prolific time of changes.

Natalia says that a previous family had returned her to US social services when she injured another child.
Couldn't the Barnett have done the same? Wasn't it possible for them to just "undo" the adoption?

A core (and very questionable) aspect of capitalism is that it's based on competition, not on collaboration (Darwin vs Margulis). I am not an expert in economy but from the little I know I have the impression that the capitalist system is based on inflation and it can't work without constant expansion, although some lukewarm regulations exists to avoid absolut monopoly.
I can imagine the 4 days system to work in smaller Companies that manage to survive without ambitions of expansion. The Chips and Fish example you gave in another comment for example. In other words, if the Company wants to keep a Status Quo rather than "growing". In that case, it could be possible to pay the same money for less hours and it's reasonable that productivity would "stay the same".
But many people are greedy. They want more and more. They would not want people to do the same in less time. They would want people to do more in the same time.
Why should these people adopt the 4 days system?
And, besides the "make them see that it's good for the Company" kind of argument, is there also an ethical talk about it? Like, "it's not so important if it's better or the same or a little worse, it's just needed and it must happen because people can't spend their life working"?

what Country are you talking about?
and what institutions might prevent such abuse?

I personally am a hardliner for sovereignty.
It's super simple: everybody has complete absolute sovereignty on their person.
People shall be free to kill themselves however they like, and this shall be even facilitated so that they don't have to find gruesome methods for not having access to peaceful ones.
If they don't want medical or psychological care, NOFUCKINGBODY, not even their family, has the right to say otherwise, PERIOD.
To prevent a situation where someone e.g. gets Alzheimer or something else that makes them allegedly unable to decide by themselves, everybody at 18 should fill a mandatory paper to decide if in such cases the doctor should listen to them, even if they seem not in their "right" mind, or a given person or familiar should intervene.
And it should be mandatory to update such paper tot x years.
Problem solved.

If there are particular cases where this is not possible, I can't say now, but this should imo be the BASIC, and the rest can be seen step by step or case by case, with ABSOLUTE priority to the respect for the individual's sovereignty.
