That did exist in the US Northeast when I was a kid. Most everything we needed could be walked to. Walmart, Home Depot, and other chains eventually killed off all the walking distance mom and pop restaurants, grocery marts and shops.
Update: I've also stayed several months in Chile, which based on GDP, HDI, and Gini Coefficient, is a more developed country. Fuel is twice the price as in Panama, pedestrian infrastructure is well maintained, and the car driver culture in terms of following rules is the opposite of Panama. Mom and pop shops are the norm there, everywhere I went.
