I think we apply conspiratorial thinking to things way more than we should (though I think the basleine for conspiracies we should believe in is zero in general), from individuals to large scale ideas. Most people are not thinking about the specific ways to hurt someone or a group of people as much as possible, they simply don't care when that harm happens.
Most abusers are not doing math in their head to figure out the perfect way to manipulate their victims, they're just self-centered and cruel and they take advantage of opportunities that present themselves. Most abusers are not thinking "these are the steps I need to take to isolate my partner/child/friend/etc from everyone but me", they're just possessive and controlling in general.
In the same vein, most corporations are not thinking up ways to poison water sources or put lead into food or make cars more dangerous to drive; those things are just the consequences of cutting safety measures and labor rights to make a profit and corporations care more about the money they make than the harm being done, especially when the only consequences are a slap on the wrist. Marginalized groups are hurt the worst by this not because there is a targeted effort to wipe us all out but because we are simply not valued by society as a whole.
It's very easy to fall into this mindset because we don't want to think that our pain is often just a side effect of someone's actions, but the reality is that there isn't some grand conspiracy or a huge chunk of our society who are evil geniuses solely dedicated to hurting people. Most people are just. . . selfish and cruel and more focused on themselves than on how they're hurting other people. There is no shadowy group of people steepling their fingers as they plan their next waste plant to deliberately poison a town's lake. That just isn't what's happening.
