$200k on a car and $7M on a house is all fine and dandy, but man, the $1.2k jeans is just way over the top. It's like you can get a perfectly serviceable equivalent for a quarter of the price.
$200k on a car is probably too much (once the novelty wears off) - you can get a nice luxury car with more performance than you can handle for $50k.
As for housing, it depends on the location. Zuckerberg's $7M house is actually relatively modest. You can buy the same house in the midwest for probably under $500k.
Even still, those things are relatively justifiable. You can't measure denim jeans worth by square footage or horse-power. I understand the difference between a $30 pair of jeans and a $200 pair (having been stupid enough to shell out that much myself), but beyond that I cannot really justify the cost.
