There's nothing wrong with newly acquired wealth, so long as you don't act like it was. While most of the strict old world prejudices against the new money set have died out with the times, the whole "Nouveau Riche" mentality is still frowned upon in every caste.

Let's just say the tacky, flashy, and braggy need not apply.
