mistyrains,
what governments have tried to "have a more efficient simpler system " ?
"Ethnical", do you know what it means ?
One of its meanings is "pertaining to a group of people ", which I am, - an Australian citizen.
"Ethical", means "right conduct and good life", which I have always tried to live that way.
If you don't understand that 1% tax is nearly nothing, it is a waste of time discussing any more with you, because all we are talking is BS.
