The proliferation of Hanlon's Razor has been one of the most damaging things to society.
People as a whole are not incompetent, every individual (and every grouping of individuals) have goals and will take appropriate actions to achieve them with intent, but somehow a neologism has tricked people into believing this is the exception and not the norm.
There's two different questions here: one is "is the way things are currently done stupid" (to which the answer is often "yes"). The other is "can a random outsider do better just by thinking about it" (to which the answer is usually, though not always, "no").
It's the same principle as another comment I made a few days ago ([1]). It's not hard to identify problems that really are problems, but finding effective and feasible solutions to those problems is often far more difficult, especially if you're an outsider. The mistake isn't in identifying the problems, it's in thinking that you can come in totally blind and know how to solve them. (Or, put another way, in thinking that you as an outsider can tell the "dumb and easily fixed" problems from the "horrifying systemic nightmare" problems.)
It's because most of the time people see mostly powerless people trying to do their jobs and messing up. They don't have as much of a frame of reference for how powerful people act, especially because there is so much mystification in the media (literally owned by the said powerful people). The rule you apply to your friends and co-workers isn't suitable for the maniacal supervillians running society. Of course, those guys also fuck up in bizzare and stupid ways too, so people will point that out and be like look, they're just bad at their evil jobs!
