Interesting article, Kevin, thanks.
Some feedback for you:
Para 1. By 'purchase', it seems you mean 'credit'?
I'm sure we agree that social cohesion is underpinned by things other than trusted commercial transactions (such as shared values, ethnicity, etc.)
Para 2. I think wealthy financiers probably introduced private debt rather than 'communities'. I imagine you agree that interest is counterintuitive because it increases risk and reduces trust on both sides... because it increases the burden on the borrower and therefore the risk of default... it is there to protect the privileged position of the lender.
Para 3. This is where I start to get lost. Public Capital sounds to me like public funds in govt coffers. How is it different to socialist enterprise?
