It's not the boomers' fault, they were misled into believing the social security system they were paying into was a genuine savings system, not just a perpetual wealth transfer system from the young to the old.
How were they mislead?
From day one, Social Security was a "new money pays old money" scheme, the one thing that makes it Ponzi-like.
To be fair, the boomers got screwed in the 1980's SS reform to pay for their parents (but had it sweet before), so maybe this is just paying it forward.
It was really FDR who abused wartime power to make a constitutionally illegal program. Now we’re in a complete demographic mess which is basically unsolvable because the pyramid is inverted.
