This is an 80s kids movie. And 80s kids bands. Or more specifically, 80s teens stuff.
I was born in the 80s, and I think I watched this movie once but it was definitely less a part of my cultural upbringing than OG power rangers and Ace of Base, lol.
Set up a philanthropic trust, invest it in a relatively safe mix of stocks and bonds, and set up distributions as a % of growth to a bunch of institutions I think are super important.
After buying a nicer house and paying off family debts and stuff of course.
Why the hell does the Swedish Chef care about this?
