Countries without these sort of provisions tend to be... "unstable" at best.
Could you explain what you are talking about here? Will the geriatric hordes smash their walkers through the glass of Apple's cube stores if they don't receive trillions in tribute?
The "geriatric hordes" have sons and grandsons. If the State doesn't support Granny, it's Father who will have to, which will leave less money for Junior, who has enough free time to go out and loot if necessary. You see where this goes.
If that family was made of civil servants or (god forbid) military personnel, you'll also have a strong feeling of resentment-fuelled rage as a bonus.
But that's how it winds up working anyway: the working-age middle class support the elderly. The only difference is that instead of that support being internal to the family, it's pooled, so that those with parents who are especially expensive to support don't have to pay more, or much more, than others.
There's some value in pooling it like that, I suppose, but let's not kid ourselves. Social Security is a transfer payment system, not a retirement savings program, which is what it was sold to people as.
I don't know the specific "implementation details" of US Social Security; my point was that support for the elderly is necessary in general, otherwise they go back to being a burden for families, lowering their tolerance levels towards accepting the rule of law. If you plan on scaling back a certain program, you better have something else ready to replace it, or you'll feel the pain at the polls or, in the worst case, in the streets.
