This is exactly why I left the field of urban planning. Practitioners were wildly out of touch with the way the vast majority of people lived that it rendered the field irrelevant. The job was basically a continued effort in trying to coerce people into living in pre-WWII style cities, when the fact is that most people who live in the suburbs are quite happy with the arrangement, even if 24 year-old me found the idea of suburbs distasteful.
