The face of rich people and philanthropy has changed too. The billionaires (and nearly trillionaires?) don't need to pretend to care anymore. They have a moat right now where it's fine to be hoarding all the money while thousands die from something which we could stop if the resources and political clout was available to help.
China was entering into this space but seems not to be helping now either, I guess because the west isn't helping, they don't need to pretend anymore that they're the good guys.
Obviously, it's the right thing to do is help, even if just for selfish reasons, ie we don't want this thing in other countries, but you cannot do that anymore because it's just political suicide to do so.
