Save our elderly

This may be true, 10 years ago a £100,000 pension pot would buy you annual income via an annuity of £16,000 a year. Today with current annuity rates the same £100,000 may purchase you an annuity of £6,000 a year or less, that is a vast difference and the reasons stated by the insurance company actuaries is long life expectancy and lower interest rates, that is fine but what can be done to help the people who are in this situation?
