I'd give a shit load of cash to bootstrapping organisations (i.e. sustainable tech) and create it as a trustfund so that any exploitable inventions got the results of the patent income.
I'd set up a chain of really high class hotels in all the major resorts of the world, and sell at lest 15% of all the rooms at loss leading prices but make there be a residency requirement that the buyer has to come from a shit-hole. They can then either have a decent 5* holiday for the cost of a camping trip, or sell it on and make some cash.
I'd support churches in Muslim countries, mosques in Christian ones, Sikh temples and Buddhist whatever everywhere.
I'd endow a school of evolution science and put it in the building next door to the creation science foundations in the states - wherever they were.
And I'd hire a very good security team.
If I was monster rich I'd ruffle some feathers.
And give money to any of the other causes that I see here tat make me laugh.
