Do away with it or keep it? If do away with it, do you replace it with something, and if so what? If keep it, what do you do to address the funding shortfall that arises in 20 years?
Keep it but modify it
Modifications change the rates change the type of investments allowed and force governments to be unable to spend or use that money except for its intended purpose.
That or start developing other investment vehicles like Canada did with the RRSP and TFSA accounts
I think that retirement ages need to be increased by at least 5 years, but probably 10. When social security was created the retirement age was above what the average person would live to. Today, most people will end up dying decades after entering retirement.
Well the retirement ages need to be increased as well and begin transitioning but in essence if you work for 40 years and the investment isn't that shoddy the retirement money should have earned a fair bit of interest.
Basically if a government is receiving payments for years and then comes up short in the end that means either they did a poor job managing it or they did not calculate correctly in the beginning which is the life expectancy error.
The best way to fix it will probably be adjusting the rates now taking that hit for this generation and building up alternative investment vehicles for the next generation to retire.
http://www.ssa.gov/oact/progdata/taxRates.htmlFrom the US History charts we can see that the cut is increasing to compensate for that presently and compound interest should well cover that in 40 to 50 years the problem is now more or less.

Rule of 72
http://www.moneychimp.com/features/rule72.htmAt the present 7.650% it should cover future retirement but assuming the government invests at a modest 3% rate that amount doubles in 24 years. (After Inflation) So 40 or so years of payments gives it some time to grow before its withdrawn.
