Indeed. I'm sorry Redspielened, but there's nothing insightful about describing money as 'fictional'. It's only 'fictional' when you've a lot of it to spare (as the often gauche extravagances of the wealthy demonstrate). For the vast majority of people money is very much a 'reality'.
It wouldn't seem as pretentious if he had given all of his money away to charity or something. Instead, he purchased a $150,000 car.
