I don't know, seems like a very weird subjective reality you're trying to push in an objective one. I am one of those people, yet I haven't had any significant problems with my work ethic.
Pushing a narrative that these people are "gonna do something to us" is a weird one to push. What's gonna happen? We're gonna be kinder to one another? We would want to make people around us happy in a profoundly human way rather than a shallow one?
