One thing people haven’t touched on is how socialism could be more effective at fighting obesity. At the end of the day, farmers produce surplus calories for the rich world far beyond the per-capita caloric needs. Sellers are able to create demand so farmers can get paid by making high calorie foods unsatiating and ubiquitous, which creates an energy surplus as the population level. An obesity epidemic is implicitly a policy decision.
Production could be planned to meet caloric and nutritional needs for the entire population if a society looks past the profit motive. Furthermore, certain food ultraprocessing methods could be better-controlled to contain foods that are basically poison for the body’s energy balance
Paris is actually quite close to New Caledonia…provided you go through the center of the Earth. I’m sure controlling an island on the other side of the world is a trivial task that the French will surely succeed in! /s
