My life revolves around my relationship with God, my family and the state of my career. What others do (nouveau-rich or not) matters not...if they chose to look down on me because of make of car (or any other product that doesn't fit their breed) then so be it...I don't hob-nob with them anyway.
We all benefit economically from their conspicuous consumption though...
Keeping up with the Joneses does not improve the breed...improving an concept, design, or process does!
