Even if you don't go to that extreme, you look back only a few generations and even today at immigrants, and you see that the old people never stop working until they're literally bed-ridden.
They might not have GDP-increasing jobs that show up on balance sheets, but grandma watches the kids (effectively working as daycare, off-books), grandpa fixes things, and so on.
By demanding everything be reduced to the nuclear family (or smaller) we've created an unnatural situation on never seen before on a global scale.

Yes I believe this brings up one of the more poisonous elements of social security, even if it is worth it. It completely decouples the mutual assistance where the parent and grandparent form a symbiotic relationship in the interest of raising the child. Instead of a quid-pro-quo, the government violently enforces a one-way transaction and the older generation can simply tell the younger generation to kick rocks.
Obviously I don't think the elderly have any responsibility to do daycare or fix things, but the fact they can simply not do so while demanding the counterparty still keep up their end of the bargain -- has consequences. If the older generation can tell the younger generation to kick rocks, then the younger generation ought to be able to tell the older generation they can kick rocks back to whatever private savings/investment they have.
