Growth is over globally except India and Africa due to demographics [1]. Developed countries and unions will compete for the last of the world’s young, prime age workers over the next century. Financial stability will be a function of who manages this situation to the best of their circumstances. Can you attract and retain these workers and leverage that for economic success? If so, that’s where investment will flow and capital will remain invested. My thesis is Europe is best positioned to succeed in the near term, based on the above.
Sibling comment mentions Europe needs the US for energy; Canada has known fossil gas reserves of ~200 years and LNG export capabilities, and Europe is scheduled to end Russian fossil gas consumption in 2027 [2]. The world is deploying 1GW of solar every 15 hours; like the rest of the world, everyone will arrive at energy independence/sovereignty eventually through cheap renewables (solar primarily, but also wind) and battery storage (LFP and sodium most likely, as of this comment) exported by China to the world. China is also selling inexpensive EVs to as many global consumers as they can find (while internal sales of battery electric and hybrids is already at ~50% this year). This leads me to believe the future of US oil and gas is an internal petrostate similar to Russia, not an energy exporter of relevance far into the future.
