Sounds like a good idea to me, the super conservative and the wealthy will be hit the hardest and that's how it should be, poor people living month to month don't have much in the bank so wont suffer much...a one off 10% tax, the pain will be short and it will be over quickly.
The wealthy would of benefited the most when the economy was riding high, so only right they pay the most.
R U 4 real????? bet you voted for the ALP, its the RICH and WEALTHY that employ people, we need the rich and wealthy.
