Social Security is a government ponzi scheme, but those people that you think should be means tested have paid into the social security system, and the benefits are merely the return on the forcibly withheld "contributions" from the earnings of the "investors". The benefits - based on the amount of earning from which Social Security taxes are withheld - should not be reduced just because you either saved or made better investments prior to retirement than someone else. Such a policy that would further confiscate your benefits just because you have better prepared for retirement than others is the epitome of government welfare and income redistribution.
The government has not represented SS as a "retirement account" with a real principle...or characterized FICA as "investment" in decades. When it was resprsented that way it was by a politician and NOT on paper (written law). How else could they allow those who never contributed a dime collect benefits?
Why do you believe it is now a retirement account in which people have invested?
