You guys are talking up SC, as if it's the Hamptons, yet you accuse me of having "blinders". Yes, SC has 'some' expensive areas, that is known as the exception, not the norm. As does almost every developed country, however, their expense ranges in the tens of millions.
So does the rest of the world. Hong Kong?? Singapore? London?? Just follow the money center banks all over the world that is where you find the rich people for the most part.
