Somehow I actually yearn for the days of robber barons. At least they found socially productive ways to build monuments to their own vanity. If Musk wants to spend $20 billion to build social housing in cities across the US, I'm not going to complain if he slaps his name on the buildings. At least Carnegie built libraries.
It's because the modern day wealth disparity has no equivalent in human history, at least to my knowledge. Maybe slavery - but they were at least valuable enough to shelter and feed.
Elon Musk shows in this just how much worse he is than robber barons.
