Lower birth rates? Short term economic pain of a graying population for a long term gain.
While birth rates are lowering enough that the population based on current projections will start dropping in a few decades, UN projections also clearly indicate it will start increasing again soon enough, albeit at a slower rate. To avoid that would take substantial further reductions in birth rates beyond that which is baked in based on current trends. EDIT: Let me adjust this a bit. UNs World Population Prospects…
Awesome!
Seriously, which is it? Either capitalism is going to fail because there aren't enough workers, or it's going to fail because robots are taking all the jobs. Can't have both!
Because, of course, having both would be fine... no catastrophe, life continues as normal as it has in the face of every prediction of imminent disaster. We have less workers due to demographic changes, but that's cool because we need less workers. We sort out the political problem of how to stop all the money going to to <1% of the population, we're all good.
