Tony it was the same at the entrance into the city, sometimes people claiming to want to live under the shields would be permitted in, only to realize they did not belong. Living under the shield naturally bought out the true nature of the cities citizens. Under the shields, there was no crime, no poverty, no one was better than anyone else for any reason. There were no bills. Everyone worked in a capacity that suited them and benefited the city they lived in. The markets were always full of fresh food that came every day from all over the world. Animals were not slaughter but killed humanely, peacefully. Everything and everyone thrived even reptiles. In fact, didn’t the snakes walk on two legs after a time and communicate using language?
