i feel like there should be a job that makes money by 'expanding' the city. you know, putting up facades, squelching empty lots, etc
maybe there could be something like a 'franchiser' or 'real estate-er' that makes more money per-tick with each lot he owns (with some regard to the quality of the lot), and gets a bonus given by the city for each lot he sells but can't sell lots for above a specific, mandated amount (set by the mayor?) to keep him from just monopolizing the lot trade
