My @Quora answer to What should a very intelligent person of 24 years, with access to significant financial resource…

I’m not going to give a direct answer (do this), but rather I’m going to go after a way to shift paradigm which you might find useful in your quest.

I’d also note that this is from a US perspective and the perspective of having run businesses.

Get back to basics by bringing the Questions down to a personal level (small scale) and then scale it up from there while holding on to those basics.

Here’s some of the core concerns you may face:
Personal safety: When you have large sums of money available the nut jobs and sociopaths do come out of the woodwork (I’ve experienced this at a much lower level). So… what ways can you use to distance yourself from them?
Every professional money manager/adviser/corporation is looking to get their hands on the money (increase their percentage). Some, not all, are sociopaths, and it isn’t usually easy to identify those until after it’s too late.
You want to do good with the wealth you’ve been gifted, and live comfortably at the same time. How much does that take, assuming worst case returns over your lifetime (say a 0.5% or 0.75%) yes, you’d be losing money due to inflation but does that really matter if you end up at age 90 with 10x or 100x the amount you need?
For me, any amount of money beyond 2x of my living expenses quickly became more of a burden than a boon. I’m never going to quit working because, quite simply, I’d be bored out of my skull.

Here’s some core facts in considering how to help folks on a large scale:
Economies (almost all of them despite the “conventional wisdom” of Trickle Down “Economics”) are driven by spending from the masses of consumers… the middle class and the poor; whether it’s an exporting nation, or an importing nation, all economic growth is driven by consumers spending. No spending = retraction or stagnation.
Money isn’t a goal for economic growth (or personal security in life)… it’s “just” a lubricant, a useful one, but also a fungible one.
So… back to basics. Given what we know and can prove by history, the Question becomes one of “How can I most effectively leverage what I have to offer into a tool which serves the most people, and make it self sustaining?” Rather than one of “Ok, What do I do now?” (Which leaves you open to being gamed)
This simple shift makes it possible to step outside conventional money management tools and create something which will offer reduced profits per transaction in the short term (say 1% to 3% Net, Net), but could well allow those funds to seed something which helps millions; and by the sheer volume of transactions and sub transactions becomes self sustaining and even marginally profitable.
Since small businesses are one of the most efficent forms (they already have a profit motive built in, and aren’t bound to shareholders profits as an overarching goal) of supporting actual economic growth from the bottom quadrants. This might be an Avenue to consider using very low interest loans or small grants of $20 k to $50 k, when those loans get paid back the profits can be plowed back in to increase the fund, and thereby increase the number of loans available. Wash, rinse, repeat.
The advantage to this is that small businesses plow almost 90% of their profits back into local economies, (per the S.B.A.) which allows other small businesses to hire more folks because of that increased consumer demand… Actually, the consumer demand is pretty constant, but the consumer purchasing power ebbs and flows as the money supply at the local level changes.
Good luck, hope this helps.
