I must be missing something huge - it looks like to get any income from the Corporation I need real estate, a production line, a sales desk, and employees. All those are an arm and a leg, seemingly outside the pre-Legendary cycle potential. So I haven't been working on my corpo skills, since the one I did had no apparent effect (since I had no production) and the theoretical boost listed had disappeared in two lifetimes from attrition.
With no way to build a Network since I've been ostracized from the Community, I'm spending a lot more time each life Schmoozing so I can hit baseline Intel needs. It's slow going, about 1 Retirement boost every other life.
