In any case, the point I think is important, and which I wanted to make, is "more pie, not dividing up the same pie" which works with both our stories.
Edit: oh, and I think it's probably not true that the people at the bottom are having a "harder and harder time". It of course would depend on which metrics you pick, but I generally understand that sort of sentiment as popular in the media but wrong in a Better-Angels-of-our-Nature kind of way. I could believe that people at the bottom are getting a smaller share percentage-wise, but the actual amount of pie they're getting is growing. People are living longer, healthier lives, there's less food insecurity, etc.
