The last few years have been a difficult time for enemies of industry super funds in the Liberal Party, the finance industry, the Business Council and the media.

What were supposed to be some long-awaited comeuppances for the employer and union-run sector not merely failed to work, but backfired on their enemies.

A Productivity Commission inquiry commissioned by Scott Morrison intended to replace the default super allocation system that favoured industry funds recommended a new model, but along the way demonstrated that industry super funds were far superior to retail funds controlled by big banks and AMP.
