Pareto principle. The minority of people anyways did the heavy lifting with many coasting. DEI got rid of like half of everyone to have more browns. Because browns are the most important thing, some of those replaced were heavy lifters. If you had even some mild retardation in management (many did, they got DEIed to) its possible you accidentally shoahed most or even all if your heavy lifters and now you literally can't do anything at all.
