Before the advent of old age systems like pensions or Social Security elders mostly suffered through high elderly poverty rates. The current system is certainly better, because elders are not starving or forcing themselves into sex work to pay for food and medical bills [1] but now it turns out being too idle might also be problematic.
I know in Japan, there are attempts to address this with organizations that hire seniors to do part time jobs like sweeping and cleaning. It mostly serves as an optional supplement to income and it gets them out of the house if they’re alone. But the way we run cleaning operations in the US is also to run people down to the bone.
[1] - This is a thing in South Korea where elder poverty is much higher than the rest of the OECD due to a very bare social net. https://en.m.wikipedia.org/wiki/Bacchus_Ladies
I’m in favor of a strong social safety net, but geared towards helping low-probability or unforeseen circumstances, not for avoiding a completely visible and very slowly approaching cliff.
* I do recognize all the problems with this assumption, like the fact that older people can continue to be productive in retirement, even if it's not necessarily economically productive. I also cringe at the idea that a society is always hyper-focused on productivity. Despite all that, I also know it's a common viewpoint.
