One of the fallacies most pertinent to some of my recent posting on the topic is #3 on the list:
I don't know the source of the numbers the author used, but whether they're accurate or not, the important point is that Social Security is not something that one can depend on, but many people do depend on it. It's not just the elderly and disabled, but also working people who put off or don't bother with saving for retirement on their own because they foolishly believe that Social Security will be their retirement!“Fact #3:” Social Security provides a foundation of retirement protection for nearly every American, and its benefits are not means-tested.”
Reality: Social Security provides a foundation of dependency.
According to the center, Social Security “encourages private pensions and personal saving because it isn’t means-tested — in other words, it doesn’t reduce or deny benefits to people if their current income or assets exceed a certain level.” This is far from the truth. Only 10% of the working population have privately held saving accounts, leaving 90% of the workforce with Social Security pensions as their only backup. As discussed before these benefits are subject to change by the swipe of a pen. Thus, Social Security is the only means necessary for most Americans of all income brackets.
There's more in the linked article than just this point. Another interesting tidbit that I had not heard before: Social Security may keep poor minority workers poor by taking their wages and putting them into a system which largely will not benefit their heirs should they die before the given retirement age. Had those folks been able to save that money in their own accounts, they could leave something behind for their heirs, which could in some cases break cycles of poverty.
