It is a Leftist myth, one universally cherished, that government as a CULTURAL form can somehow be superior to the people who constitute it. Take all the people who work for the Federal Government, and put them to work in the private sector, and they are in the Leftist world diminished somehow, even granted the same morality, same competence, same jobs.
The Social Security Administration, in this peculiar and entirely unexamined way of thinking, is inherently more virtuous than those same people administering private pensions and personal retirement savings, EVEN IF in the latter case vastly more money would be available to the public, under their direct control, and not being made available only through an intergenerational Ponzi scheme, which is bound to crash sooner or later.
