We are almost two decades into the age of billionaire philanthropy and what’s results has it produced? Can you point to any area where it’s really changed the world?
I think a fundamental problem is that the non-profit/NGO sector doesn’t have the same caliber of people as the private sector. There’s no Jeff Bezos equivalent working on inner city education. Bill Gates is really the only one who has tackled this, by investing his own time into public health, which I understand has produced real results.
I understand Gates has also helped in reviving Nuclear power, from reading news on this site and others. Smaller, updated designs that don't face quite the same level of pressure from regulators.
If we assume you are right about billionaire philanthropy being basically ineffectual (I personally agree) there is a line of reasoning that I find explains why adequately. When systems don't have their incentives structured properly, then quite often the unexpected outcomes are stronger than the predicted outcome. Because the input to the system did not properly account for, or change the incentives which drive the dynamics of the system.
Examples about in healthcare, social programs, education... large SWE companies...
There's so little real pressure for results when you're backed by some billionaire's fortune, the existence of the organization is not threatened by non-performance... there's no free market to survive in, the goal is to lose money... the things you are trying to measure are slow signals or mostly qualitative...
We're a century into it at least, even in nominal dollar terms, starting with Rockefeller as the first billionaire.
I don't know whether John Arnold is spread too thin or not, but he's certainly top caliber and does a lot to measure progress before/during investment in various causes (including education). He also seems to be more agnostic on what the most appropriate solution may be at the beginning of the process.
The Gates Foundation also put a lot of money into education in the US, but my understanding is that it’s had mixed results. Public health seems to be easier.
Sounds like you may have read it but the book Winner Takes All is about this topic and pretty enjoyable.
I think there's a case to be made that philanthropy produced the Internet Archive but maybe that's a little different from usual philanthropy since Brewster is very hands on for so long.
