Single family homes aren’t the problem, it’s lack of density and mixed-use. Ideally you have single family homes mixed in with condos and apartments, coffee shops, grocery stores, etc. and then you mix in various sizes and configurations so the wealthy CEO is walking their dog at the park and saying hello to the student living in a studio apartment, and they all say hi to the elderly couple sitting on the porch when they bring their kids to school to their neighbor, the teacher.
Taking each of these and creating a “suburban neighborhood” area, a retirement home, a shopping complex, and a school complex and making each of them require a personal vehicle to get to is solely responsible for fucking up America and other Anglosphere countries to a degree.
