I was living, now circa 8 years ago, in a big city, now I'm living in the french Alps and I have exactly ZERO intention to come back in a prisons named city.

USA suburbs for my little US experience have a simple issue: they are residential ONLY. Here we have sparse homes AND commerce of various kind, in few km/miles from my home there are a handful of other homes, but also a small supermarket, a blacksmith shed, a brico-like shop (semi-finished wood like panels, lumbers etc and metal products, paint, ...) a multi-service small center (from tobacco shop to parcel shipping and so on), as a result we move of course, but much less than in the USA.

In cities on contrary instead of living in nature, moving in nature, we commute between big buildings used for less than half a day, to seed physical ads (shop windows) in between them, wasting a gazillion of natural resources, being unable to evolve due to density, being in a thermal mass island to augment the effects of climate changes, having waterproofed so killed, a vast area of soil, created subsidence problems, disrupted the natural water cycle for a much bigger then the city radius, ... to the point nearby some coastal cities sharks get too much cocaine from humans.

Dear city-lovers: in the past cities was NEEDED, not a good place anyway but a needed one, because of scarce, slow and expensive logistics, paperwork who need offices, absence of modern TLCs etc, nowadays cities have grown big enough to being unmaintainable, ghettos for poor and desperate slaves of the finance capitalism who NEED CITIES to keep up, the sole, without any other purpose. Did you now the Green New Deal? Well, allow me, since I've built a new home, with p.v., a bit of energy storage, BEV etc to tell a thing: the Green New Deal work. But work ONLY in small buildings, single family homes, hens etc. NOT in cities. Oh, yes you can theoretically build new cities, the Saudis knows a bit with their failed Neom project, failed like the ancient Fordlandia or modern Arkadag, Prospera, Innopolis, ... smart-lagers for citizens-inmates to be exploited by giants, so costly we can't even build a first generation of smart cities, while we can and we build and have already built countless new green new deal compliant homes. Cities are modern mainframe, needed by the cloud+mobile world witch is a fragile and distopic one.

To correct suburbs just buy and destroy some homes there if the density it's too much and insert some sheds with various shops, and you'll discover how is easy to live with them. Than you'll discover again the strong-town classic physical work from home with the barber shop in the basement and the barber's home on top because hey, we have hairs to be cut, teeth to treated and so on whenever we live, so instead of having X dentist in a dense area of a city we have the same number of dentists spread as we are spread. The sole who loose are the giants because in single family homes we own and we are naturally pushed to own instead of rent, there is room for LOCAL economy while giants struggle to be spread and so on. If you want a clean planet remember cities are polluted and incompatible with nature, humans are part of the nature and integrated in it live well.
