I dont understand how people can compare two or more difference places unless they have lived in those places for about equal amount of time. For example I really cant compare the life between Chicago and London because I have lived in Chicago but not in London. Similarly I can compare many aspects of life between the US and Canada because I have experience of lliving in both the countries for number of years each. Similarly I can compare between Chicago and Toronto because I have lived in both the cities for number of years. Similarly it will be rather absurd for me compare Toronto to London because I have lived in Toronto but not in London.
