Do they? I dunno. In Europe we had a regular ritual of hauling kings and the like out to the town square and hanging them. They knew where the problems originated. Of course, the Kings and the Lords did exactly the same thing to the plebs, and a lot more often, but eventually the elite came around to the idea that ordinary people aren’t playthings, and that life would go a lot better if we could all just get along. It took about 600 years, but we got there in the end.
It’s just my opinion, but I suspect there’s a co-dependency thing going on there. Both the elite and the plebs benefit from the status quo in that they all get to do the things they like doing. The plebs get to feud with their neighbours, and the elite get to pillage the country. Everyone’s happy.
I realise there are structural reasons why people feud (eg., lack of a functioning justice system, or bad laws about land tenure) but those reasons are theoretically fixable. It’s just that nobody really, truly, wants them to be fixed. Or at least they don’t want it badly enough to actually make it happen.
