So? What's the functional difference between $6 billion and $1 billion (which is roughly what Google says his current net worth is). Unless your net worth is $500M or more, you're closer to being homeless than ever seeing that kind of wealth.
It doesn't make sense to accuse someone of not feeling the economic impact of a downturn at all while downplaying the fact that they actually lost $5billion.
Tell me, how did his lifestyle change as a result of losing this $5 billion? What actual pain of loss did he feel, above and beyond seeing some numbers go down?
If you were serious or had devoted any thought into the issue you wouldn't even consider the silliness of framing a $5billion loss as a lifestyle issue.
