All these things need to be done. My thoughts center around how do you provide a decent sustainable existence for the other 2-3 billion people on earth[1]. There are a lot of things that need to be done to make that happen. Really affordable basic healthcare is one of those things.

[1] Hint we can't do this via the raw growth and exploitation used to lift the first billion people out of poverty.

Yes, all these things need to be done. But, again, most of these things will matter little if in 30-50 years much of our planet becomes uninhabitable, which is now nearly certain unless we take immediate action.

Those 2-3 billion people on earth you mentioned? Most of those live in the tropical zones and if we do not concentrate on fighting climate change NOW, will not have a place to live. Healthcare will be a secondary issue.
