>>In addition, participation should be voluntary, just like health insurance was before 2009.
Why, apart from ideological grounds? Look to the Australian Super scheme. Wailing and predictions of doom at the start, these days success has many fathers. A predicted asset of $10T by 2028 for a country of 22M people. An equivalent scheme in the US would have had $140T by 2028 rather than the status quo that has social security going broke by 2037.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
