I think the Early settling game, with the -1 population is now a major nerf to Progress, leaving it struggling in the early game vs the other two branches. It can scale up well, but a early game disadvantage can really stack up. I've played games with all three early game trees and Progress seems the slowest to get rolling, and the easiest to derail with aggressive neighbours.
Tradition gets a opening 2 population to the capital, along with some extra food and growth. This makes pumping out early settlers not particularly damaging. Authority gets a free settler and makes it much easier to take enemy cities or muscle them out of a area. But Progress gets no bonus to settlers, beside a single extra movement point. This runs counter to the aims of the tree which is supposed to be about a wider empire then Tradition, with more of a core empire than Authority. It's food bonus is late in the tree, often behind only Equality in terms of pick order. And three food isn't that much.
So I propose attaching to Organisation, a food refund after creating a settler class unit. Not a full refund, but a good chunk of how much it cost to gain that lost level. Not a world shaking bonus, but a boost that can allow a faster settling of settlers, without crippling the capital.
