Political commentators can debate the merits of one policy over another as much as they want.
The reality is a law was passed (By the Liberals in 2000) allowing franking credits to be refunded. People were encouraged to save for their retirement by offering to refund unused franking credits. People acted on that and put additional money into super. Some of us have been saving and investing for our retirement for 18 years based on this. Many of us are currently heavily invested in the ASX because of the tax advantage that we get as a result of the franking credit refunds.
Maybe someone can elaborate on the idea of taking lump sums out of super or closing your super fund as mentioned in this article
