Basically, the uber rich want to be seen as something more than just money. Guys like Anschutz and whatnot. There seems to be a pattern where they get a new shiny glass and steel building with a bunch of sick kids in it, and then they put the wife's name, an ampersand, his name, and the last name in big 3-D letters on the side. Likely it's a tax writeoff.
Also, not to be too cynical, but it's not a bad thing overall. The money could be sitting in the Caymans afterall.
