Pretty much my whole life I've had three intermittent sources of income which required many, many hours of work. I did this to get ahead and to be independent in retirement. Now, a couple of years away from that glorious day they want to change the tax laws to rob me of planned super income as well as tax me more for the arse busting hours I do so they can pay extra to people who, in many cases, can't be arsed trying any harder. I'm happy to pay my share to give people a leg up, but I'm stuffed if I just want to pad the pockets of unionists who see it as their right to get as much as possible for doing as little as possible.
Where's the incentive to work harder? Flattening tax rates minimises tax creep which actually gives people value for working harder. Why not just bludge along, never aspire to anything and then grab a handout from the government at the expense of all the other saps trying to get ahead. As for people on $250k - well they're paying 10x the tax of someone on $45k so that's a fair difference in accumulated rate.
I don't know what the perfect tax system is but it should be one that encourages people to work harder, earn more and naturally pay more tax - not get it forcibly taken with tax hikes. Laws should be encouraging people to fund their own retirement instead of relying on the pension.
FFS our politicians are idiots.
