In these cities, stores will return to what they were in the 19th century. All the goods will be behind the counter, with perhaps some non-functioning models on display. The contrast will be in low crime towns and cities where self-checkout will come to dominate because people pay for the goods. On-line purchases to secure locations will also continue to expand in the Seattles and San Frans of the world.
Nice stores will move out. Stores left will have big ugly gates, double doors and thick glass cases. Ugly stores for ugly communities.
Create incentives and rewards for criminals and you get to live in a hellhole.
