>entire generations have grown up agreeing with you because literally the density of the pre-car era was eradicated and they know nothing different.But a lot of people have experienced high-density living and deliberately reject it and choose the suburbs. Consider a common life timeline:
- early 20s (single no kids) : going to college in a big city or starting a career at a downtown firm so they enjoy the dense city living like Manhattan, Chicago, etc. Walking to restaurants and bars, museums, cultural things
- mid-life with kids: they enjoyed cities in their younger years but they want to raise a family so they move out to the suburbs. Multiple reasons could be the better schools, less crime, less noise, more square footage, a back yard, garage and extra space for hobbies, etc.
- senior/retired and kids are grown leaving an "empty nest": some (not all) senior citizens might sell the suburb house and move to a city condo and walk to museums again. But some also stay in the suburbs and just move to a smaller house or single-level townhouse.
Yes "walkable cities" have advantages but the suburbs also have particular advantages that can have higher priority. It's not about ignorance. It's about prioritizing which advantage is most important.
