Don’t agree with your contention, except for that last sentence, which correctly points out the problem is fraud not honest PRE-PAY recipients to SS and Medicare.
Regardless of how the Ponzi is processed inside the government, it does not change the facts that those that are legitimate SS drawers did PRE-PAY at 15% of their income their whole working life.
Most folks who have not yet talked with SS Admin, may be surprised to learn that they can not collect any SS if they do not sign up first for Medicare. A second surprise is that Medicare costs us very close to standard health insurance by the time the 1st part of deducted from your monthly SS, Part B and Part D (you pay to some private insurance company) runs another big out of pocket cost. And again, hardly some freeby entitlement.
