Most Australians at this time have insufficient super as they approach retirement due to it's commencement date and the low level that the compulsory super was set at. It was a wage trade off as part of the Accord process.
In places like Singapore it is around 20%.
So for some time into the future the government will have to top up super with pensions. The real hassle is that 12.5% or 15% or 17% is not enough. The goevernment will still have to contribute.
Most Australians are unaware of this till it's late in the day believeing that they will be OK.
The income from super is also unprotected.
If you have a self funded super you can control your investments to some degree e.g. property purchases. For those on industry or retail funds most is in the stock exchange and thus is like going to Randwick and punting by using a pin.
If I have the funds in my pocket I can choose what I do with it and also don't pay fees.
The above site might prove interesting to see where you stand in this situation.
