What is never mentioned in articles like this is that the post-war period was a truly exceptional period in one respect: literally almost everything was supply-limited. A bit less so in the US than in Europe. Now it's the opposite: almost everything is demand-limited. If you asked a good economist "what factory needs building?", the answer would be none. Or the answer would be something like "the EU is about to outlaw calculator imports from China, build that factory". One of these environments makes it much, much harder to grow. Obviously this is a general trend, not a rule.
