Exactly. These large 'world class' cities are great to visit for their cultural treasures, but who would want to live there? They're also great for the wealthy, but not so much for the ordinary person fighting the congestion everyday to staff these playgrounds for the rich. Take a look at the faces of the daily commuters and tell me if they look like they're enjoying themselves. (By the way, Toronto is only a 'world class' city in terms of its cost of living. It is lacking in all the cultural treasures that make London, Paris, Rome, New York etc., worth a visit.)
