Yeah SS was never intended as global retirement, it’s just morphed into that.
What’s kinda interesting is that a large part of the national debt is essentially SS buying “stock” in the US government in order to get some sort of return. Every month millions of Americans contribute to SS so we have to issue more “debt”.
Using quotes because this is overly simplistic. State pension have normal portfolios, I think MI actually is heavily invested in my company… not sure what the effect would be if SS could buy VTI.
Also interesting as much as Fox and Friends like to scream about China buying our debt, the biggest foreign debt holder is Japan. Japan has an incredibly old population, comparatively, and they buy treasuries for their national pension plan. China has actually decreased their holdings.
I think if you look at US debt by sector, all retirement esk holders so mutual fund, pensions, SS, life insurance, etc both foreign and domestic make up the vast majority of debt holders.
Anyway the whole system is supposed to be a backstop, therefore no risk tolerance.
