Some gamble. Some do drugs. Others buy audio equipment. We all have vices I guess.
I remember being on vacation in Vegas a few years back and my wife was shopping for purses. I was shocked at the fact women didn't hesitate to spend $1000 on one. A freakin purse!! Here in the Midwest that is a house payment.
I suppose if you have a $1,000,000 house, $250,000 car, 2 ex wives, 3 children and a psychiatrist, $100,000 for a home theater makes perfect sense.
I guess it's all relative.
