Universal healthcare is not a panacea, and it doesn't guarantee equitable health outcomes. In Australia, indigenous life expectancy is 13 years lower than the life expectancy for the rest of the country. That's mostly due to preventable illness in a first world country with universal healthcare. I imagine outcomes for New Zealand Maoris and native Americans are similar.

The world will need to learn to deal with shrinking populations at some point. Economic growth is not, in my opinion, a particularly compelling argument. All systems have physical limits, and the extensive collapse of the biosphere suggests that our level of population and economic growth are both unsustainable. Aside from the cultural stagnation that an immortal aristocracy would represent, it would be an absolute disaster for the planet.

As for the wealthy sharing for their own benefit: when has that happened in history, ever? Extraction continues until the peasants storm the gates. In the short term, it's cheaper to invest in better security.
