"I make my own investments and cringe every time I have to pay 9% to my employees that can't think for themselves."
Time has obviously faded your memory (but not mine). It is not you who is paying the 9% superannuation guarantee levy. It is clear that anyone familiar with the history of it's introduction, and capable of thinking for themselves, could not possibly draw the conclusion that they, as an employer, are having their wallet touched.
A bit of history.
There were two steps leading to the introduction of the superannuation guarantee. Firstly there was to be a reduction in income tax as an offset against wages and salaries not increasing in line with the cost of living (CPI). Can you recall Keating's "Read my lips" statement? Following on, because of economic circumstances the Hawke Keating government decided not to reduce taxes but to introduce the superannuation guarantee.
The beginning point is the increase in the CPI. An increase in the CPI is, in the absence of compensation by means of an increase in income of employees, a transfer of income from the wage and salary sector to the corporate (of which you as an employer are part). The ledger says, then that it is not you who is contributing the 9%. It is the employee.
A little further thinking on you part would also bring to mind the thought that you have no doubt benefitted from the reduction in income taxes which have been facilitated through employees self funding their retirement.
Keep cringing but stop trying to justify your attempt to double dip.
