You need to widen your scope Ben , as it is the whole tax system that is stuffed.
Too many loop-holes, too complicated, too many taxes. Just impossible to police and few of us want to pay our share.
In 1985, the Keating Tax Summit found that one direct tax on turnover of the top 10 Companies would be enough income to cover a comprehensive Labor Federal Budget. Eventually GST was born from this, but was a watered down tax that will never do as promised.
I personally favour turning everyone when they reach 70 into usable byproducts. It would save heaps on health and aged care, make more housing available, get money back into the economy from inheritance and give all those Christians a firm date on going to Heaven. I used to think 65 was OK, but I am not far from that, so 70 seems a good time.
