As Goetzman says, "finance reorganizes power." Like the masters of any technology, the financially strong will dominate the weak. That is natural, and there's nothing we can do about it. But capitalism without a regulator results not merely in the wealthy influencing government policy. Oppressive income and wealth inequality grows naturally from unfettered capitalism. So does corporate conduct that puts others at risk -- that victimizes others -- for the sake of profits. I'm thinking here of the likes of Boeing, ignoring safety concerns to push its 737MAX onto the world's runways, https://www.cnn.com/2019/12/23/business/boeing-dennis-muilenburg/index.html
, and the Sackler family, who made and squirreled away over $10 billion from the opioid epidemic that their company enabled, https://www.bloomberg.com/news/articles/2019-12-17/how-the-sackler-family-shifted-billions-from-opioids-to-trusts
. This is what unregulated capitalism excretes, and it matters little whether we call it an engineered "system" or as natural as the gastrointestinal tract.
