@wakame Yeah, I condensed it a bit. Like, if you exchange access to resources for labour, and the resources are limited but labour is basically renewed overnight, and you want the capital to mostly remain in the hands of who has it already (for power/system stability), then today's labour has to be worth less than yesterday's, and preferrably you'd want to increase the amount of resources whereever possible ('reserves'), usually making renewables into non-renewables via exploitation.
