I would argue that its an engineering/technology problem at heart. If access to those things was easy and cheap politicians would have no/less incentive to hold it back. It's probably not the same if it's a limited and restricted resource.

If we had more people trying to optimize food production, water distribution, Healthcare scaling and management etc, those things would become materially better, fast.

But we are more concerned with optimizing ads so we can buy shit we don't need so..
