Well first off have Taco Bell stopped providing napkins? One person couldn’t find napkins in one store and suddenly it’s greed driven corporate policy according to OP?
It seems unlikely that a food chain would completely abolish napkins. It is possible they’re no longer freely available because people were taking them “for their car” whatever that even means!?
I think a lot of it comes from schools, and in particular physical education and competitive sports. There is nothing wrong with competitive sports but the attitudes around it in schools can be so toxic, and in particular it can be used to create hierarchies. The idea of being good at sports and that being masculine was something I certainly experienced a lot at school. Also people who weren’t as academic but thrived in sports were lauded.
My school had various sports teams and clubs, and fuck all academic activities. Sports aren’t toxic but the attitudes around them can be, and particularly adults who feed in toxic attitudes and values around it.
