Imagine buying a condo for millions of dollars only to find out that the building the surrounds it has sunk over a foot and has tilted 2 inches.  You probably wouldn’t feel too good about your purchase, would you?  The Leaning Tower of Pisa (or, as I thought it was called when I was 7, “The Leaning Tower of Pizza”) wasn’t supposed to lean either, but they were able to turn lemons into lemonade and make it into a gigantic tourist trap.  That’s a luxury that I’m not sure the Millennium Tower in San Francisco has, unfortunately.
