The problem is unrestricted, unregulated capitalism. Get rid of the top 20 billionaires and others will take their place, just as bad or maybe worse. Regulation goes a long way to addressing many of the problems we are seeing in our world today. Is it the only solution? Definitely not, but having had most regulation gutted (started in the 80s and just getting more hamstrung from there) has escalated the problem immensely. Reintroducing strong business regulation is a good start because, contrary to what a lot of you all are hoping for, most folks aren't ready to seize the means of production and make a wholesale change to a socialist utopia.

I genuinely do not understand why my point was so hard to grasp. Billionaires are bad, yes I agree, but billionaires are the end product of a system that allow billionaires to exist. Do not only focus on symptom, focus on the cause.
