I really thought this was an interesting article and the comments at the bottom made it the more interesting. The comments at the bottom where made by voters.

Apparently having money and doing whatever you please now days is frowned upon.
Think of all the people employed to build and maintain a 90,000 sq ft house. All the labor and all the material suppliers. So what if you think it's too big and not what you want. I personally like my 1800sq ft house, and could not imagine walking around in a house that big.
