At the very least, it would take enough automation such that the elderly don't need to either work or get wealth transfers from the working population to survive. Wealth transfers to the old only work when you have many more working-age people than retired people; if you don't, the whole thing implodes. It would also take a society where people don't need investment appreciation to have enough wealth to live on, which again requires a much larger amount of automation and economic abundance than we have now. It's not impossible, but it requires the kind of deliberate effort which seems beyond our political capabilities at the moment. The abundance people are at least aiming in the right direction though, hopefully they get more of a foothold.
