I think you're dead right, actually. I do think that because you have limited resources, you tend to find that people look around for allies. They form groups. Those groups become tribes. Then you're really off to the races.
I think you've offered a very good answer and a very good diagnosis to some of the things that were said by earlier speakers and some of the questions that were posed. When they were talking about what has gone wrong with DEI, it is perhaps in large measure the fact that when you have a movement to try to compensate some people who have been historically marginalized, those people are hungry and eager for this to happen quickly. They want to consume a larger share of the resources than is being prepared to be given to them. They form alliances. Then what you start to get is a competition that can easily turn internecine, and this is not good.
This doesn't come out of simply the lack of resources. There are occasions on which groups of people, realizing there's a lack of resources, can do better than that. I think what is needed, always, is the ethical perspective. There needs to be a place where ethical discussion happens among people, where people reach compromises and where they agree to share and take away less than what they had originally thought they needed.
