Won’t disagree with you on your points, but your math is off. 1.6% on a $1000 SS payment is $16. Medicare increase will gobble about half of that. As they say in German, “es Macht nichts.”
I think he meant that all but $1 would go to increased Medicare premiums.
Many people have their Medicare costs directly subtracted from their SocSec check each month.
I worked for New York State, and they actually reimburse retirees in our pension checks for our Medicare costs. The Feds take it, and the State gives it back. I do pay for my secondary Medical coverage from the State, but since it’s just me, the cost isn’t very much, and they usually only cover my medications, which is fine with me. President Trump’s tax cuts gave me over $2100 back in my pocket this past year.
