Retirement is going to be effectively pay-as-you-go no matter what you do (at least until we invent much more sophisticated robots).
You can't stockpile nurses and save them up for when you retire.
If you save money or invest in financial instruments, you're still relying on labor from subsequent generations and if there aren't enough of them, higher labor costs will eat up everything you saved.
The only way to really save up for retirement on the society-wide scale is to spend money on things that increase the productive capacity of future generations.

Indeed, and we didn’t do that. We invested in issuing debt and other non production capacity efforts.
