Whatever "they" are going to do will happen, someday.
But I don't understand how people can think "it" might happen suddenly, overnight, without warning.
The last time they messed seriously with SS was in 1983 when they increased the full retirement age from 65 to 67. That two-year change was phased in over a 22-year period, with an 11-year hiatus in the middle at which the retirement age remained at 66.
Whatever happens, there will be ample warning.
Can you explain this? How did your claiming age affect your medicare payment?
