My wife's grandparents are were lottery winners 20 years ago. They won the Florida Lottery. I think they made out with 6 million after taxes.. They already had money and It was only 6 million (6 million was a lot more back then), but there were still plenty of unpleasant situations.
Family members with great plans for businesses (those failed), scammers at the door all the time. Real estate investments with huge tax payments..
The first thing my wife's granddad did was go to Dollar General and but them out of his favorite shorts. They are very down to earth people, so it didn't kill them.
I still hold out some hope that they invested some wisely or squirreled some away... But I ain't holding my breath.
To be honest though I'd hate to be in that situation.. You can't help everybody, even though you want to. I've had money, and I've been broke. Happiness is not closely related to money. Love can't be bought, though people always try, and love is the only thing worth having
