Interestingly, so did FDR: "In a written statement to Congress in 1935, Roosevelt said that any Social Security plans should include, 'Voluntary contributory annuities, by which individual initiative can increase the annual amounts received in old age,' adding that government funding, 'ought to ultimately be supplanted by self-supporting annuity plans.'"
Now that's a real blast from the past. Is it "ultimately" yet?
ANOTHER UPDATE: It looks as if FDR was talking about a different portion of the Social Security plan. This would have involved, essentially, a sort of government-supplied 401k plan.
Why can't Brit?
