The other transition is the bulge in the elderly population. This seems to me to be the major economic issue in developed nations. In Australia at least, government spending on the aged is the number one expenditure at $70 billion, not including healthcare spending. That’s about $18k per person over 65. The proportion of elderly will increase then plateau at about 1 in 4 over the next 50 years. I’m not sure the numbers add up... it probably only works with ongoing population growth which will have to come from immigration.
