A few years ago I visited South Afrca where the average house was surrounded by a concrete wall. South Africa has many villages and rural communities of impoverished people where the main goal each day is to find a clean drink of water. However, people throughout many of the towns and cities lived behind walls.
Brazil is another country I’ve visited a couple of times where steel bars in windows and walls around houses are prevalent. Thieves and robbers are common in Brazil and South Africa and it is understandable why they want walls around their houses to protect their valuables and families.
