Idk, most of the people I know who majored in urban planning, even getting masters degrees, have quit and gone to tech because they are literally not allowed to implement any of the empirically proven ideas on the urban landscape. All of those decisions are made by city councils who are completely beholden to private property developers, and as such, urbanization is sporadic, piece-meal, and not based on any real kind of planning. Easier just to make money in tech using your engineering degree than fight with private property developers. Pays more too.

Hell, even a Robert Moses like project would be considered too radical for most modern day urban planning in the U.S.
