the underlying point is that money isn't the be-all-and-end-all of what we value and what we exchange in our socioeconomic lives. money collapses a multidimensional social calculus into a single-dimensional metric, with all the undesirable consequences of that kind of collapse. hoarding wealth is selfish, but it's worse when it also hoards power and esteem along with it.
not many wealthy people deserve respect (or power) along with their riches. people who make stuff with their hands and brains, not passively through wealth (e.g., rents), deserve esteem. that's the point.
