It is also very unclear when it is talking about "family income", and when it is talking about individual earnings, two very different things.

I would also like to know who is in those top income brackets, most likely it includes a large proportion of public service employees. I should know, I was one. The salaries of my colleagues still employed  have increased substantially since I retired ten years ago.

Funny tidbit, I was talking recently to an academic couple making over $300,000 (family income), who cancelled their two newspaper subscriptions, to the Globe and a local newspaper, because they were getting "too expensive"...
