The real inequality we have today is being perpetuated by outdated regulations, primarily from the 1930s. It's also being perpetuated by people that invest in Warren Buffet-style "value" stocks, which extract actual rents from people, while delivering no technological improvements. Housing is 80% of the inequality problem, and if we are going to fix that, we have to stop making it illegal to build enough homes for people that need them. And to do it cheaply enough, we have to turn to automated custom home manufacturing, which means overcoming the objections of labor unions.
For example, I just saw this in the LA Times - "Labor unions, environmentalists are biggest opponents of Gov. Brown’s affordable housing plan":

NB: I think we need new, distributed structures to replace labor unions, because the goal they serve is an important one. The existing ones concentrate power at the top, and have become just another corrupt institution.
