According to this Forbes article Bill Gates is worth about $52.8 billion today. Forgetting for a moment that most of that money is in the form of stock shares assume you had that money available to spend. Let’s also assume that you want to keep $5 billion dollars for yourself since that should still allow you to maintain whatever lifestyle you have become accustomed to leaving you with $45 billion to blow.
What would you do with that money?
Me, I’d buy Chicago a new mass transit system. I’m tired of riding the loud, crappy El. Of course, with that money I doubt I’d be riding the El anymore but I love Chicago and woudn’t forget the crappy rides I experienced on my way to the top. Having no real idea how much such a thing would cost I’d still be surprised if the bill came to more than $20 billion for the latest, greatest mass transit system the world has seen yet.
With the remaing $25 billion I think I’d buy the Sears Tower and make it my home. IIRC that building should run around $2 billion to purchase. Obviously that’d be a ridiculously stupid building to have as a house and I’d never likely see most of it but who gives a crap. It’d be conspicuous consumption at its greatest! Add in another billion for refurbishing I’d leave my remaining $22 billion to pay for upkeep and a squad of missile toting guards to shoot down any airliners that strayed too close to my house.
