Historically, the best off maintain their largess by making sure there are enough in the fat and happy middle to not support a revolt by those left to deprivation and exploitation.
It's reasonable to be fat enough and happy enough that you don't want to rock the boat and don't mind that others have "more in their bowl", which is why this pattern persists through geography and time, but you might want to keep an eye out on how the worst off are doing, whether they're growing or shrinking, and whether things are getting worse or better for them because the other part of the pattern is not unprecedented or unreasonable either.
