Agree.It's not about dollars, but about percentage. Higher income earners already pay a higher dollar figure of taxes than lower income earners. They gain from tax advantages on investment income. Dividend franking, capital gains discounts, etc.
To put it another way, a broadbase, higher GST will take away more, in % terms, from lower income earners than higher income earners. To me, that's the definition of a regressive tax.
We were talking about this at work a couple of days ago (yes; I have a mechanic who is actually intelligent and can discuss these things on a decent level - he's a Labor Lefty, but I won't hold it against him too much).
We would rather see the Income Tax brackets decreased, and all income tax lowered generally.
Then, the GST (or consumption tax) is lifted to say; 12% - but not on staple items such as clothing, "generic" food (purchased from places such as markets and supermarkets, and not from restaurants, cafes etc - places where food is already prepared and sold to eat; these should be subject to the GST) and utilities.
This way; the battlers can save money on the things they need, and everyone gets hit a bit harder if they choose to be a consumer.
And - I know folks will scream at this - all overseas online purchases attract a 20% GST.
If you don't like that; buy locally. Too expensive? too bad.
Start thinking about the economy of this Country and improving it and the future of jobs and not your own selfish hip pocket nerve.
