"There are not many workers (proportion of total) who earn enough to get a mortgage on houses that sell for over a million dollars each."

Today, take nothing for granted.  So, you have to define "worker."  Just recently, a column in the G&M indicated it's quite possible for two household partners to earn incomes of, say $85,000 each--and there are many, many who do --and have the cash to make a  minimum down payment on a home that's over $1 million.  MInd you, they're eating Kraft Dinner a lot and eating out a lot less to make the mortgage payments--but that's another issue.

So--don't have the stats on this, Dr. but it does make me wonder--what "(proportion of total)" households in the Greater Vancouver area cannot manage to do so...especially, when so many already have significant equity in the home they now live in.  

Can you do a little digging on that and let us know?  And define "worker", while you're at it.
