today, there are 64 million social security beneficiaries and 164 million working people in the US. Who is going to pay for social security, when these numbers are reversed? how can a country such as South Korea, when it gets to over 50% retirement-age people, produce "high value", let alone "increasing value"? who will be taking care of their health and doing physical labor? > long as the value of the produced work increases Assuming that this is only a problem for "high-value" societies is incorrect - Indonesia, for example, while still not as bad, is almost below replacement rate, so who is going to take care of 273 million non-high-value people there once they get old?
