According to the Georgia Guide Pile-of-Rocks, the earth should only host 500 million people. That means 7.5 billion must die. That means 15 out of 16 must die all at once in some catastrophic event. (or slowly over the next few decades?) If monetary value was the only determining factor, how much money would you need to be in the top 5%? Based on net worth and income, to make the cut you'd have to be worth at least.... a million? wait... 10 million? I can't figure this out, but it's a number that can be calculated based on available figures. I'm just not savvy enough to figure out what the top 5% of net worth is. I'm pretty sure there aren't 500 million billionaires alive today.
