Chelsea Clinton's wedding guest bathrooms cost an astonishing $15,000 -- all you have to do is look at the gallery to see why.

The luxury porta-potties looked better than most people's home washrooms with wood cupboards and a beautiful backsplash. There was also a stereo so you could rock it out while you are on your throne. Chelsea Clinton's wedding guest bathrooms show us little people what it is like to live large.

Implications - The world of luxury goods has, in recent decades, expanded beyond Learjets, Cadillacs and expensive colognes. Companies have found it extraordinarily profitable to add a touch of opulence to ordinary goods. Interestingly, this concept is applicable to nearly every good or service industry -- from toiletries to taxi cabs and from gardening equipment to action figures. Businesses willing to embellish their products with a degree of class are likely to see returns on those ventures.
