Lets face it compulsory super was the invention of the Hawke Keating govt way back then. It was devised to create a power over workers money by the unions, and I emphasize "at that time". Workers traded off pay rises for super, it would have been a better system had it not spawned a massive ancillary industry by way of advisors, planners, insurance they account for billions of lost savings for the average worker who is unable to see what the actual charges are.
I don't think Hawke or Keating (and Kelty) would be very proud of the system as it stands. It was a trade off at that time to prevent a wages explosion and the only reason they didn't put it under govt control was to appease the unions, now to the detriment of small account holders.
