and it produces more than the owner”
I believe the Keynesian talking point on this is the “multiplier effect”. That term was bandied about ad nauseum during the stimulus era. The idea being, if you give a buck to Joe, then he spends it at the local shop, the shopkeeper in turn spends it elsewhere, and so on blah blah blah. Then they produced a “study” that said that the “multiplier effect” created something like $1.20 in value for every $1.00 put into the system.
So there you have it.
Next on my list of “things to do” is alchemy. And other forms of magic.
