Increase the Social Security Retirement Age

The minimum age to collect full Social Security benefits today is 66.  Between 2021 and 2027 it will rise steadily to 67 years of age.  

What if we raised the age of eligibility for full benefits by one year per year starting in 2015 until it reaches 70 in 2018?  

That would reduce overall spending by about 1% of GDP per year which would only delay the point at which the Debt reaches 100% of GDP by two years - from 2023 to 2025.  By 2050 the Debt would grow to 282%.
