Suppose you win 100 million. What do you actually do with it? Banks only guarantee 250,000. Do you have to invest it? Is there anywhere you can just let it sit and draw interest?
When you win/exploit/inherit/etc enough capital to live well for multiple lifetimes, it always perpexes me when people fixate on making more.
You won, go enjoy hobbies you can easily fund now, it's just hoarding at this point. Capital is a means, and it's kind of pathetic when people warp it into their end goal when it's no longer the key limiter to their lifestyle.
It's no different than hoarding newspapers, but at least many of those hoarders often demosntrate the self-awareness and recognition of embarrassment.
For 100 million you are good but for more realistic amounts of money the value of it just goes down with time so it is a good idea to do something with it.
I think the behavior of hoarding is pretty human and there is a broader failure of inequality.
If you gain sufficient amount of money (we are talking 100M $ here, but it works even for 1M), you have SO MUCH MONEY that it can generate money by itself within a reasonable timeframe AND you can live really really well with it, enjoy your hobbies and free time, all at the same time. And if you don't know how to do it, let a professional help you, because you can pay for them, too.
Let's say you have $100,000,000 dropped in your lap. You now never have to worry about needing money ever again, which in our current society means you don't need to worry about a LOT of problems.
So it's natural that most people want to preserve that security, the best way to do that would be to invest the money in a way that it grows equal to, or faster than you will spend it.
You can just get it all in cash and stuff it under your floorboards, but there's a non zero chance that the money will be physically destroyed or stolen from a disaster.
You can stick it in a bank, but you have very little protection for the bulk of that money from the government insurance.
So the smartest thing to do is to spread that money out to investments that will grow that money in a diverse way to protect your newfound security.
Once that is set up, you create a will (or trust) to handle the money when you are dead. Who gets to benefit from your windfall once you're gone?
Then you have complete freedom to live your life how you want to.
