America has transitioned quite nicely from wood to coal, coal to oil (for mobile apps). It will transition quite nicely to the next denser energy source if the government would butt out. Same is true for natural resources. The price mechanism of the market is mighty and very effective. Is it perfect? No. Is it a lot perfecter :) than socialism? Yup.
The other thing this article ignores is that the world is about 20 years away from a population crash. World demographics have shifted dramatically. My son will spend much of his adult life with the government frantically trying to impose socialism in order to prevent population collapse.
The country that faces that in the worst way is China, thanks to their draconian Maoist-era population control laws. They’ll have to either bring in lots of guest workers to manage the geriatrics, or go all Logan’s Run on their asses, or have a huge war in the next few years to clean out the surplus menfolk.
The US will grow enormously over the next 85 years.
