I would keep 2 million for my family and myself. The rest would go to women's shelter, rachel's vineyard, catholic relief services, retired religious and many other charities. My God children would be taken care of too.
Assuming it was tax free? I'd give 2 million to my mom. I'd probably give a million to a good friend of mine. And I'd give 2 million to charity.
No reason I can't live comfortably on 5 million bucks.
I would buy a lamborghini
I'd bank a million and arrange for the annual interest to be donated to a charity of my choosing, probably the local childrens home
some to friends, most to the irs
Buy and island and donate the rest.
