Wealth like this sounds great to those not that wealthy, but those experiencing it often aren't any happier than those who have their needs met. Look at any of the tech (b|tr)illionaires; do they seem as genuinely happy/content as the neighbor down the street who gardens regularly and has a tight-knit group of friends and family they spend time with?
Don't get me wrong, money is great! But the "keeping up with the joneses" never stops. You quickly adjust your mindset and feel poor compared to your buddy who has 400 million dollars.
