Nice link, that part where your scrolling while seeing the billions going up takes like forever.
I clicked the url because you read your comment saying if they gave you $1,000 that would be 0,0001% of their wealth but that would be only true if their wealth was exactly one million. But we're talking about billionaire, and if a billionaire would give you $1000 he'd give you 0,0000001% of their wealth. If they have 10 billion it would be 0,00000001% and if they have 100 billion it would be 0,000000001%. According to Forbes there are over 20 individuals with that kind of money.
