Just call the franking tax refund change what it is a rich tax.
limit tax refunds from franking credits to $20,000 p.a that means that anyone with investments over $1,000,000 get cuaght out top end of town, and the poor baby boomers who worked thier arese off to just have enough super >$854,000 for a couple but not enough for a pension still get to keep theirs.
THen the majority of self funded retirees would be happy and vote labor in, as they too think someone getting $250,000 in franking credits is a rort.
E.g couple have $860k in super earning 5% per annum pension phase $43,000 Franking Credits of $18428
Total income $61428
lets just say they are drawing out $60,000 for a couple. P.A and can live comfortable to retirement.
if change happens they will be only getting $43,000 P.A - they will chew up their super and be fall back into needing the pension to supplment their income, and they might get a dollar or two there but have a lower quality of lifestyle.
