When you pay into Social Security and Medicare for all of your working life, expecting to get some of your money back is not an entitlement. These idiots need to understand the difference.
No, it is exactly an "entitlement." You are saying that, because you (or others) were forced to have payments for these programs deducted during your working life, you are *entitled* to benefits at retirement age. That's what the word means.
The details are a matter of debate, both philosophical and economic. To what, exactly, are contributors to SS and Medicare entitled? A return of their contributions? A return of their contributions plus interest? All the medical care they want for the rest of their lives? The medical care an insurance policy would provide if the present value of contributions were available as premium?
And then, there's the question of what can be delivered (assuming the best of intentions, although we know that's a false assumption when government is involved) under economic and demographic conditions that are very different from the assumptions when the programs originated.
