Barry Ritholz highlights the alarming debt to income ratio for Canada compared to the USA:
How does Australia compare?
Australian household debt to income is similar to Canada’s. There has been discussion recently about whether Australia is in a housing bubble. As Anna Schwartz (joint author of A Monetary History of the United States, 1867-1960 with Milton Friedman) pointed out: there is only one kind of bubble and that is a debt bubble. It may manifest through rising real estate, stock or other asset prices, but the underlying driver is the same: a rapid expansion of the money supply through easy credit.
