Ye, u tell how stay healthy with prosperity. But u miss, that no real point to stay healthy until endgame.
Staying healthy is worth +10% production, science, and culture. Those are pretty good benefits. Which Industry benefits are you claiming are worth more than that, to say nothing of the non-Health bonuses, like worker speed, border expansion, +1p Basic Resources, and +3e per TR or +2e per specialist?
I mean, +25% buildings is good, but many of the main-line industry virtues are just "get more energy", which is pretty weak, and certainly not better than the Prosperity energy virtues.
