Well, I don't have time in any one session to really go in depth and build factories as I need to, and upgrading them all is an expensive nightmare. It would be lovely if my 60,000 or so Capitalists I've focused up could do some of the heavy lifting themselves (I even had to build most of my level one railroads myself, AI did the rest) but they seem to just sit on their collective rumps, even though half are getting luxury needs met. I think State Capitalism is making it too expensive for them, but I have no options to switch away.
