Similarly, medical assistance is paid through taxation of the current work force, so it puts a lot of stress in the economy, as taxes necessarily have to be increased. In my country, they have opted now for reducing medical assistance (which is provided entirely via taxes, managed by bureaucrats), so clinics on cities that people go to retire have been closing. First, the emergency room, now its the entire service.
But then who would work to pay for the care of the elderly? I am no expert in economics, just an autodidact who started studying it to not look like an idiot when others were discussing it, but I personally like the idea of savings on commodities. Its true that they oscillate in price -- demand can be especially alarming as people discover ways to go without them -- but supply tends to become more expensive, and there are always uses for them. And you can diversify. So social security should just keep reserves of oil, metals, etc.
