This is something I want to drum from the rooftops - the political effects of a handful of billionaires is vastly overrated compared to the sheer number of "merely" wealthy people. Your local zoning issues aren't because Jeff Bezos has taken a personal interest in destroying the lives of poor people in your neighborhood, it's because there are enough doctors and lawyers and children of doctors and lawyers acting selfishly to protect their investments.
In this regard, I wish more people would read Progress and Poverty. The book is a lightning flash of clarity. Especially in the last decade, it has become shockingly prescient.
