In Latin, communiatates datum translates over to meaning gated communities.
Whether you agree with the idea or not....I would suggest over the next forty years....this philosophy of gated communities will expand out, and roughly 10-percent of America by 2060....will live in a gated city, a gated down, or a gated suburb.
Chief reason? The general denial of most people to settle on expectations and lack of political stability. You could have a fine mayor or a fine governor....but if the attorney general of the state, or the chief prosecutor of the city won't really do their job, or the judges just grin and look the other way....you end up with approved chaos.
Back around eight years ago, there was a statistical review, and it was believed that around six to nine million Americans lived 'gated'. If I were guessing today, it's probably closer to fifteen million living 'gated'.
For roughly twenty years of my life, I worked in the Air Force, and you got a fairly good taste of gated-living. You passed an ID at the front gate, and within that 'land', you generally felt safe and the odds of robbery or assault was almost one-percent.
In areas like Atlanta today, your safety/stability view is probably only around seventy-percent....meaning that you continually look over your shoulder and keep a firearm in anticipation of trouble. If you live around Baltimore, your safety/stability view is probably closer to forty-percent. Don't even bother bringing up Detroit or Chicago.
You may argue about the philosophy, but people are making judgement calls, and looking at the best way to survive.
