It's time for an inheritance tax
"One of the world's most celebrated economists has suggested the Turnbull Government introduce an inheritance tax to help address rising wealth inequality, which is making it increasingly difficult for middle-income Australians to buy their own homes....
It struck him as odd the Australian Government imposed no taxes on those who had been bequeathed multi-million-dollar properties, while governments in the United States and Europe taxed the same gifts at between 40 and 45 per cent."

Makes sense to me.
Its odd that Australia seems to be one out in not having inheritance tax.
