The essay falls on its face with its central thesis that 2010's Canada = 1970's Soviet Union, which beyond being absurd on its face the author fails to make any case for other than observing, correctly, that bureaucracy exists in Canada and that individuals that are established in a social hierarchy take advantage of it. The underlying motivation for this screed seems to boil down to 1) rents are too high in Vancouver, and 2) firms don't want to pay techies enough in Vancouver. This is then extrapolated linearly to mean 'Canada'.
As for the observation on the housing situation, this is recognized generally as a problem in many markets, but his actual argument here is that these high rents thus smother "wealth creation". This may be true in Vancouver, but doesn't seem to be true in other areas like the Valley or NYC, which remain hotbeds of economic activity. Vancouver's specific problem seems to be that the Soviet leadership in British Columbia has been unable to curb the very capitalist problem of money laundering profits from the People's Republic of China into Canadian real estate.
