This started as a reply to this good post and kind of grew to be only slightly related, so I'm making it its own post.
a few years ago someone made me notice the "hidden constraints" people have for solving problems and how most of the time we don't even notice they're there until someone points them out.
Yes to all of this.
I think I first got this idea into my head some years ago after reading a blog post about road design. It was written by a former engineer who used to get frustrated because local residents would object to what he knew The Research said made roads as safe as possible, until he realized that he, and The Research, always had the unspoken higher-than-safety priorities of moving as much traffic through the neighborhood as quickly as possible.
And yeah, money / the continued wealth and power of the already rich and powerful are hugely common hidden constraints. But they aren't the only ones, by far. So much baffling/frustrating/self-defeating shit that cishet men do, for instance, is because their #1 priority is the esteem of (real or imagined) other men and they're absolutely unable to admit this to themselves. And, similarly, so many people refrain from living a life that makes them happy because the idea of not living up to certain social class norms-- which can have real consequences, don't get me wrong-- is just not one they're willing to face.
