I think HN specifically, and the country more generally, has become disgusted with the magnitude of wealth concentration.
Very few here probably believe Ellison, Gates, Bezos, Page/Brin, Elon, or Zuckerberg don't deserve to be very rich.
But that reasonable "very" is 2-3 orders of magnitude less than their current net worth.
That's what many people feel is the broken part of end stage capitalism.
