Heh heh, you said:

You made no mention of how the $100K account was to be funded.

after I said:

"true interest rates are 4%, that means about $8000 of 12k in earnings will have to come from additional taxes heaped on the rich."

"Certainly that is currently the case: many families approaching retirement don't have that much saved. "

Not families, sir, individiduals.

You are quite right that such a program would increase the tax burden tremendously if everyone had a fully funded account. But at this point, the wealth inequality in the US is pretty high, and it will take some drastic action to equalize it. It will not be hard making sure the burden falls mostly on the rich.
