Yup. One area where this gets particularly interesting is healthcare - older people consume quite a lot of it, it's highly skilled and hasn't been particularly amenable to automation, it can't be stockpiled at all, and healthcare investment mostly seems to increase the amount people consume and the price of it.

Of course, generally you wouldn't exchange your assets directly for food or healthcare; more likely you'd have stocks and bonds and make money from some combination of selling on to non-retirees and taking some of the profits when they buy things from those companies, but it's ultimately what you're doing in the end.
