Financial capitalism where everything needs to be consolidated, bundled and sold as an investment vehicle seems like a pretty modern invention.

To go to an extreme, look at It's a Wonderful Life. Something like a community bank in the early 20th century was not run aggressively for the sole benefit of shareholders, there was a notion of community involvement. If anything financialization since the 70s has created the fiction that corporations are soulless machines designed to optimize profits at the expense of all others.
