That's far from clear. For example, from the article, turns out Sting costs $1m for a private performance. You could get a private concert on Saturday nights, and in 15 years, your money is all gone...
I double dare you to listen to a sting album every night for just a month while considering 15 years of it.
You really can't spend that kind of money. So what do you want to do with it? What do you want to do with your time? Time which is a resource of yours that is actually scarce when you have stupid money so it is not scarce at all.
Both of those probably retain some value. Property may appreciate.
I really don't think you guys have thought this through. All your suggestions on how to spend underline that it's basically impossible, even when that's your object rather than enjoying it. So now who are you giving money to? It's the only thing you can do with it. Children, good works, politics, immortality via a wing of an art gallery is popular. A building at your University... Gates is trying to rid the world of disease.
When i say you can't in not making euphamisms. You just can't. Lay out a serious plan that you would want to try and spend it and you see it's not practical or even close.
Replace Sting with every artist you like and think on the logistics of it. It doesn't work. Rival Leno's Garage. Only stay in 5 star hotels. Private Jet. 5 mansions on different continents go nuts. Your idea of no expense spared, lap of luxury. Price it up for 70 years worth.
It’s hard to consume $700m, certainly - but you can easily spend that much money doing what capitalists do: creating, acquiring and merging businesses. Think money as a tool, rather than just as something to be converted into goods and services.
Why did this person not put more money first? It isn't obvious that you can't spend $700M? Neither can your children and grandchildren.
Long before $700M money ceases to be valuable to you. At all.
