There's been a lot of comparisons between the gilded age and modern us economic structure with respect to individual wealth.

I contend the even more disturbing mirror is the trust/monopoly/cartel structure of virtually all industries and markets in the United States.

The ultra rich are a symptom, not necessarily the cause: we need a massive breakup of practically every sector in the United States, and it's not just for what the parent of this comment says about wealth creation: increased employment, more job mobility, more innovation, overall competitive advantage in the world, more resilience to global supply chain disruption, and innumerable other national security and economic concerns.

Monopolies are really bad for freedom. As we see with the closed no-appeal ban systems of internet companies and utter lack of customer service, your very day to day freedom can sharply be curtailed at a whim by the centralized power of monopolies.
