My only concern is I do not consider SS & Medicare Payment a Tax. It is an investment/insurance in our future that We make from OUR OWN Pockets. Like an insurance policy it is a "Promise to Pay". I think any reduction in SS or lack of Medicare services is a result of lack of forethought. Therefore it is foreseen and should be corrected early. Just letting it break is not an option IMHO. If we know it will break in 2034, we are obliged to fix it, even if it means raising the percentages of what the pre-eligible folk are paying. I really hope and think that will be the eventual outcome.
It doesn't really matter if you consider it a tax or investment/insurance. What matters is what the GOVERNMENT considers it. And that is very clear, and was solidified by a Supreme Court ruling several years ago.
FICA (SS & Medicare tax) is a tax, and is not any sort of "Promise to Pay". You have no property right to an SS benefit. Paying the SS tax and collecting an SS benefit are only connected in our minds. Legally there is no connection.
Too, what you (or I) think "should" be done is immaterial, and nobody is "obligated" to fix it.
