Manager's entire job is to provide the organizational support and navigate the organizational challenges to allow the non-manager employees the space to do their job. When we talk about systemic organizational failures, managers are the ones that own that problem and are accountable for the failures.

Sure, on an individual basis, you have pockets of amazing managers that can't overcome organizational inertia. I feel for them as well, but when organizational failures come into play, I'm certainly taking more pity on the employees then the managers.
