That's because, as a singular planetary species, that story is a myth. The rich only maintain wealth by exploiting people against each other, thus deterring actions against the rich who likely caused the issue in the first place.
Lack of housing because it's a profitable investment class that rises in value due to lack of supply? Obviously it's the fault of NIMBYs alone and not political policy pushed by lobbying groups.
Healthcare too expensive? Totally not the fault of private equity bleeding care networks dry and public health insurance companies denying coverage to fund share buybacks and CEO raises, so it must be nurses striking for pay or the government for paying too little on Medicare.
The point is that if enough rich countries said "fuck this shit, pay up and fuck off out of politics forever", the rich can't leave. They're stuck here, on Earth, with the poors. That's not going to change anytime soon, so the only thing stopping these countries from reigning the issue in is cowardice.
But do you have actual evidence that we need it? (Instead of just "nice to have".) Because everybody just repeats that without evidence, like the OP.
There are plenty of reasons to expect the OP's prediction not to hold. I don't know how things play out in practice, and I don't think I've ever seen anybody that knows it.
