Ahem
Go on the internet and see if there's ANY  major city in the world where the average working stiff can afford a house within the city limits. It's well over a million bucks for a semi-detached home within 15 miles of  London, Paris, New York, Madrid etc. ( in fact a million bucks won't be enough for a down payment if you want to live within five miles).
Unfortunately that's the way it is when your city becomes so successful that everybody wants to live in it. We have no war planes flying overhead , we have no military on the streets , minimal corruption 
(although lots will disagree)and we have written the book for comparatively peaceful racial integration. Qualities like that don't come cheap.
