This is really a cultural problem that has infected management along with everyone else.
It used to be that you were expected to be able to fix your own car or washing machine, and moreover that one you couldn't fix would be rejected by the customers. It was expected to come with documentation and be made of modular parts you could actually obtain for less than three quarters of the price of the entire machine.
Now everything is a black box you're expected to never open and if it breaks and the manufacturer doesn't deign to fix it you go to the store and buy another one.
The problem with this is that it poisons the well. Paying money to make the problem go away instead of learning how to fix it yourself means that, at scale, you lose the ability to fix it yourself. The knowledge and infrastructure to choose differently decays, so that you have to pay someone else to fix the problem, even if that's not what you would have chosen.
The result is a helplessness that stems from a lack of agency. Once the ability to do something yourself has atrophied, you can no longer even tell whether the person you're having do it for you is doing it well. Which, of course, causes them to not. And in turn to defend the opacity so they can continue to not.
Which brings us back to management. The C suite doesn't actually know how the company works. If something bad happens, they may not even find out about it, or if they do it's through a layer of middle management that has put whatever spin on it necessary to make sure the blame falls on the designated scapegoat. Actually fixing the cause of the problem is intractable because the cause is never identified.
But to fix that you'd need an economy with smaller companies, like a machine with modular parts and documented interfaces, instead of an opaque monolith that can't be cured because it can't be penetrated by understanding.
