Don't bet too much on that. People on S.S. are going to be getting the biggest increase most have ever seen this coming this January. The largest ever given since the 80's. Count on that to be officially released to the public, just before the midterm elections.
Secondly, fixed income people were FAR LESS affected by the, "pandemic". They didn't lose their jobs, or have their hours cut, or in many cases completely extinguished for months. Many working people went through personal economic disasters directly because of this.
Fixed income people were able to simply ride it out, with zero change to their incomes, or lifestyles. The checks kept coming. I can say this whole thing didn't affect my life the least bit in the last 2 years. With the possible exception of having to wear those useless masks for a few months, if I went to the store.
And lastly, most retired people on S.S. or "fixed incomes", have their homes paid for, and have no debt. They also have other investments that contribute to their retirements. Many that pay on a monthly basis. No one I know who is retired, depends on S.S. for their sole retirement income. As it was never intended to be that.
