[@Viciousmarrow] We could totally break that down into upper upper class and lower upper class, and upper middle class and lower middle class...and middle middle class...

For example, Amity, Axis, Aoi and Ryoki may be upper upper class, whereas Amaya or even Copen would be considered lower upper class...

Shou is upper middle, btw. :) SCA and a PhD pays pretty damn well.
