And there's no political will anywhere in the USA, suburban or urban areas, to change any of this.
Individual families were not expected to walk out into the fields and personally make them habitable. They certainly weren’t turned away by policies designed to preserve the status quo, compensate/empower those adversely affected by a proposed change, etc.
Highway construction, planning codes, development and mortgage finance, public debt, subsidized infrastructure, etc. were all assembled and optimized to make it as easy as possible for suburbia to happen precisely as it did.
That was a choice. We could make the same choice about urbanism. (Imagine an Interstate Highway System-level investment in urban subways). We don’t.
