It goes like this all the way down until there actually has to be something tangible. It doesn't have to be good, or useful - just tangible. They give those jobs to some programmers. They are smug and think they are actually doing work, but really a programmer's sole responsibility is to give their managers something to have meetings about.
If we admitted things would work better with less worker time, it would start to undermine the whole system, and everything would fall apart. So 5 days (with as much overtime as possible) it is.
In the US, we see the ambitious, driven person as the one who wants to work (at least) 5 days a week. We want to believe that outcomes are related to the amount, and not quality, of work put in. This value runs deep to cultural values where idleness is related to sin and “wasted” time[1]. Time spent in economically fruitful endeavors is viewed as important, while other time spent seen as frivolous. Today we see it manifested in startup culture where founders humblebrag about intense number of hours worked, like they’re the true believers in this value system. Larger company execs want to emulate them, hoping their employees show the same “hustle”. Many Americans often don’t even know what to do with their free time!
So in the US there’s a lot of cultural baggage to overcome.
(Of course, this value isn’t held in all cultures, where enjoying the finer things in life has cultural significance.)

Stigma: Much like the phrase "remote work" had 5 years ago, there is a stigma around the 4 day work week e.g. for many, it's a synonym for "laziness"
Fear: if a company switches to a 4 day week, most believe the customer output will suffer. This has been shown not to be the case however [1, 2, 3]
Culture: Although it's improving, I believe there is still a culture of "work-hard / play hard" in many companies (especially those which are VC backed) - a 4 day work week is the antithesis of this

p.s. I run https://4dayweek.io - I've now sourced around 50 Tech companies which have a 4 day work week and it's increasing every week. I believe it will become major movement
I find pitching it as a “self funded 20% time project” also helps with the negative perception of laziness. I’ve been using the extra day off to learn VR game development and rock climb.
With the way the market is desperate for senior engineers right now you have a lot of negotiating leverage, and salary above a certain amount is pointless. Can’t take your money with you when you die.
The more workers who do start performing the shorter weeks, the more of the remaining workers will have to work more days per week than they are doing now.
As it stands your odds of pulling it off individually are probably better than waiting to see if it becomes adopted by the mainstream.
So there is probably widespread inertia in favor of the status quo.
My last job had me working 10 to 7, 5 days/week. That was too much and I thought 4 days was ideal.
My current job is much more relaxed. Everyone is done by 6 and we sometimes do game night. Management and HR actively lowers pressure, encourages us to take more breaks, and informs us that they've never turned down any request for a day off. Now I'm tempted to work 5.5 days/week, especially when they let me take a day off whenever I feel like it.
The problem seems to be that things aren't in sync. We're not getting enough rest or enough work done; I suspect 4 days is stressful when you have a lot of meetings. Socialising is a huge factor too - I had none of it in my last job, but I'd like more in my current job. I had no time for errands in my last job, but now that they're cool with me running errands on weekdays, I don't need extra time off.
I also work just as hard as I did when I commuted and have never been reprimanded for not getting enough done, quite they opposite in fact.
Recruiting, HR, training, etc…
The longer hours take more of a toll on mental health, rather than less.
It's a pain for childcare, trying to socialize with folks on a normal schedule, making up hours etc. Everyone else is working the fifth day, so can't really socialize then. My doctor and dentist don't work that day though, which means can't use it for appointments.
Another important aspect is that if retirement looks into days worked, you need to work 25% more hours to unlock benefits.
