The GST {Grab, Steal, Take} and all the other tax is simply because we are still treated as a convict colony.
The Government takes our money to pay a huge excess of politicians with disgraceful behaviour that i would not take from my kids when they were 4 years old, are worse than useless and cntribute nothing worthwhile to the society, and if you do not agree with the political party in power, that no one seems to ever have voted for, and do not want to support them and with hold your money rather than give them "tax" for their pay and all their rorts, then you are classed as a criminal, and instead of 80% of everything, they take 100% of your stuff and then put you in gaol !!! End of Rant.
