How About This for Fixing Social Security?

When Social Security was established the age of 65 was the minimum age and it was beyond life expectancy at that time. The government did not expect you to live to the eligibility age.

Choose a time in the future. Let's use age 25 as the age of child bearing. In 2005 a baby is born, in 2030 that baby is 25 and produces offspring. Beginning with those people born in 2030 and beyond the eligibility age is 5 years beyond whatever life expectancy is at that time. That age would be adjusted every 50 years. Beginning in 2055 people with an income, by work or by investment or by inheritance, of $30,000 over the poverty level at that time would not be eligible to receive any income from the Social Security program. That level would be evaluated every 50 years.

Social Security would not be used for any other purposes.

If you don't like those specific ages or amounts pick those you prefer, the principal is the same.
