@cd318 I had a lot of time for Keynes, I particularly liked his suggestion of burying bottles full of pound notes and letting folks dig them back out as a way of easing mass unemployment.
Our brains are hardwired differently.
The owner of the pound notes could have kept them in the bank earning interest and then at a time of unhealthy levels of unemployment allowed willing folks to clean toilets or care for the elderly for which they will be paid with those pound notes.
