The second mode is another way of doing the first, actually.

Either way, working people's output today needs to support the non-working people today (unless you let them starve). Whether that is done via taxation or via wealth accumulation, one way or another, more and more young people will be supporting old people.

And it's not even clear the wealth accumulation angle is good. It requires young people to own a lower amount of wealth so that old people can dangle it in from of them to keep them supported.

The two major differences are that in the first, no money is stored, has to undergo inflation or risk disappearing. It's also not your individual money coming back to you.

I agree with the rest.
