Never thought before about how to invest if you have enough money that four generations of trust fund puppies could not possibly go through it all. With eighty percent of the money in safe investments it would be best to use the other twenty percent to invest permanently in promising startups in new sectors so that the fifth generation and beyond would still be at the top of the heap. Better idea however is to own an international bank that lends to both sides in wars. That puts you right on top of the money hierarchy.
