Three Cities And A Common Denominator.

[jackflash]

Can one guess what the common denominator is as to WHY these three cities are so costly to live within them??? At 0:59 into the vid the three cities pop up. I added a 'scramble' below of three words for you to descramble in case you cannot figure out what the denominator is.

I was going to guess either electricity or indoor plumbing but that would rule out San Francisco.
