“Climate Change” doesn’t just make energy artificially scarce, it also adds artificial scarcity to food supplies and other necessities.
Artificial scarcity, or restricting supply as well as controlling distribution, was perfected by capitalists primarily on non-essential commodities, particularly intellectual property, which otherwise would be difficult to control the spread of without laws forcing consumers to go through specific providers.
While I would say that controlling access to something of value is not new, and would go as far back as hunter gatherers giving up nomadic life to protect a food supply or natural resource and forcing others to trade with them for it, but now it’s the marxist/globalists who seem to be in on this game. They realize that restriction of access to LIFE ESSENTIAL commodities is POWER to a level much much more efficient than violent oppression, because it cows the masses into submission without the need to administer distributed means of force.
Restricting supplies of food so as to facilitate control has been part of the government playbook as long as we have histories of government.
The Sumerians did it. The Egyptians did it. In more modern times, the Holodomor in Ukraine and Pol Pot in Cambodia are excellent examples.
