So there are a few versions of this.

The most common in the US is the strip mall. This is a largely American, soulless construct of commercial space with parking out front, typically on a major road. There are lots of reasons why this flourished in the US. It's a symptom of society being so car-dependent, which is by design. Rents here are typically lower than other options so some businesses can survive in strip malls that can't elsewhere.

The next step up (density-wise) are actual malls, or shopping centers for the non-Americans. There are different versions of this. You have the entirely indoor mall. You also have other anchor stores that pop up nearby (eg Home Depot) that are popular but can't justify the mall rent costs. Often a bunch of other businesses will sprout around these stores, which is why they're called anchor stores. Anchor stores are also things you generally need in a mall to bring in enough traffic to make the whole thing economical eg supermarkets, department stores. Malls in general have been dying in droves. Basically too many got built in the 1970s through 1990s and online shopping is killing them. There are photography and video channels dedicated to exploring dead malls.

The third rarest option is the walkable district. This is generally the downtown of cities that existed before cars. People generally love these but public transit is an issue. Americans always want to drive even when there are viable options otherwise. That means having to build parking garages and the whole thing kinda falls apart. Or at least it losses some of its charm. The hellish end of this spectrum is Houston.

Some cities have managed to rejuvenate such areas by diverting traffic and generally investing in the area. But what tends to always happen is that businesses will rejuvenate an area and then the landlords will kill it by charging exorbitant rents. I've seen 40+ year old restaurants close because of rent hikes in areas that only really existed for that restaurant.

This is part of the problem with housing being so expensive. It makes everything expensive. That local shops? Well it costs as much to build as a house and a house is easier to sell. But a cafe or a bakery or a bookstore or some other eclectic shop can survive when the rent is $20,000/year. You don't need to pay staff as much when houses cost $100k not $1M. Expensive housing just strangles everything. But when that rent goes to $200,000 over a decade well then suddenly only chain stores and big box retail can survive there so what was once a charming downtown turns into Chili's, a CVS and a Chase bank.

So this can go wrong even in dense places like NYC. There's a real issue right now with so-called "zombie leases". Basically, companies like CVS, Duane Reade and Walgreens signed high-rent long-term leases but then decided to close the store. The store remains empty because the owner has no incentive to rent it for a now-lower market rent while the billion dollar company is still on the hook for it. Enough of these and a street can look abandoned.

I really think that when cities choose to rejuvenate an area they should acquire all of it first. Eminent domain, baby.

I saw a Tiktok awhile ago where someone posited that things we once took for granted get taken away from us and sold back to us. The specific example was walkable cities. That used to be the norm. Now it's a luxury. We can't have that. If people walk everywhere and take a train or bus well then they might not buy a car. Then they'r enot buying insurance and gas and maintaining it. Unacceptable.

Society really is getting dystopian.
