He didn't make the money because it's unrealized gains, but your point still stands. The market certainly agrees that this is a good direction for the company, and if the market is correct, he will stand to benefit eventually
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.
If there's no functional difference between before and after the loss, it damn well does.
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.
His point, which you failed to address with your smug response, is the well-understood fact that the utility value of money falls greatly, the more money one has. The utility of 5 billion dollars is essentially zero to someone who already has a billion.
Other than ownership of an NFL/NBA/Premier League/etc sports team, what life satisfaction or happiness improvements are unavailable to a one-billionaire?
