That’s not what happened. During Covid, stuff got scarce, because supply chains got interrupted (e.g. by lockdowns in China). People still wanted/needed that stuff though and the ones that could afford it paid more money for it. the companies just “forgot” to lower the prices again after covid, since everyone got kind of used to the higher prices.
There’s a massive fusion reactor in the sky that we could easily use by turning the radiation from it into electricity or harnessing the winds that are caused by the temperature differences it creates.
Nuclear fusion still has a long way to go, but to slow climate change (already too late to stop it) we need to act now.
