I know how to fix this but I'm not "allowed to" can eat away at you easily. Then there are things that I know how I might fix but I wouldn't realistically be able to because it's all a lot to take on, there will almost never be enough time and hands to get it done, within the set constraints.

This is due to the way how incentives are aligned. Systems that are powering things for, say a decade at least but worked on Quarterly basis.

Why is this alive and well, then? Because it doesn't actually matter as long as money keeps rolling in. It is also possible that the losses caused by or efficiency not achieved do not show up in the accounts.
