I used to believe that but I don't think it's actually true.
I can't speak for Europe but as far as the USA, the evidence seems to show the _silent_ majority actually prefer the suburbs instead of 5-story buildings.
The above claim will be hard for readers to accept if they are well-versed in the constant negative news articles in New York Times, etc and Youtube channels like NotJustBikes, StrongtownsOrg, CityBeautiful, ClimateTown ... all disparaging the "soulless" suburbs.
What happens is the proponents of "walkable cities" have inadvertently created a "filter bubble" and now mistakenly think most families don't want to live in suburbs.
But what about all those surveys where people preferred "walkable" cities to go to businesses like grocery stores, theaters, and museums without a car?!? That's true but the surveys' methodology and framing are flawed because they don't structure the questions as a set of tradeoffs so the respondents can see if they prioritize other things above walkability such as bigger house sq footage, yard and pool to play in, garage for hobbies, not sharing apartment/townhouse walls with noisy neighbors playing music too loud, etc.
So the _silent_ majority in America do like walkability... but they also prioritize other aspects of residential living that ends up sacrificing the walkability. It's the unstated tradeoffs that explains the paradox of people supposedly wanting "walkability" but yet we still all end up with car-centric suburban sprawl.
