It is less OK to do it without time to plan. As I said, the plan has to include cuts and increases. Raise the cap, raise the retirement age, and there may be no need for "cuts". But it is easier for someone 30 to adjust to what will happen at 67 than someone 66. It is like steering a ship, the sooner the turn is initiated the less sharp it has to be.
Whenever this comes up, I wish we had a way of letting people who do hard physical labor reach full social security ahead of us office workers.
Here's a solution, an estate tax that goes to Social Security from Boomers. The thread is about all this money we Boomers have, take it from us when we die and pay off Social Security, and then it is there for you.
Believe me, I have had no objection to raising Social Security taxes, something that would have impacted me. It isn't my fault that never happened. Raise the cap, raise the retirement age a year, and let's see what happens. We can then look at and 1/4 point of tax with lower COLA and see if that solves it.
