Economists
Where there's an economy, there's someone seeking to master it. Even civilizations without money find themselves in need of ways to allocate scarce resources such as ideas, land, or processing power, and so almost every civilization develops a caste of people who have attuned themselves to the mysteries of scarcity. Their shared expertise becomes a sharp divide between them and those who go without. It also makes them prosperous beyond the rest.
The Economists Society is a catch-all for economics experts across the universe, each devoted to the complex systems of their own civilizations. Crossover occurs when their people need someone who understands enough to translate between foreign economies - or when they scent opportunities of their own. Advanced technology has made them capable of frightening accuracy about the flow of any market.

They learn business-related tasks faster, have reward systems tied to rational economic actions, and can better simulate the outcomes of their financial decisions. In game terms, Economists have a competitive advantage in the Financial Profession.
