Thank you so much for your insight!
It is difficult for me to relay the scope of urban planners, as I have only had a few classes on urban planning/design, and cannot speak from that side of it.
It’s true- urban planners do take care of economics more than architects. Urban planners, for the most part, don’t do the details and more delicate design aspects of buildings.
Although, I do know that a lot of architects are on urban planning boards. To me, this is a nice compromise to choosing one or the other. The two professions are so close (yet so different!), one should not have to choose!
