Dear Rusty: I started Social Security about 2 years ago and I thought that the monthly benefit amount stated to me by Social Security in their letter was guaranteed. That written amount was what I based my decision on to retire. Now I hear on the news that we may have to take a 24% reduction in the future. That will make me and millions of other seniors homeless. Was the original amount a guarantee of monthly income, and can the government reduce it whenever they want to? Signed: Anxious Senior
