If things continue to move same direction then guarded area with 24/7 security cameras and guards with own Schools shops could be the future.
All those Crisis economic and wars will create more dangerous life around us.
Gated communties could be only way for living and it seems that things are not going better all the situation in middle east will couse conflicts all over the world no question about it mixed with ukraine situation and high cost of living and economic problems with mixed many other social problems don't look good and for many people gated community Will be good way and why not If you can choose nice place and you can feel relaxed.
But instead of this many people will considering place like dubai at least you dont feel like in prison you can be around people and feel safe in gated community might be less people and not much space to go around.
But more and more safe places will be demanded from people as world we live in right now people start value safety and peace of mind.
Gated communities are just for preventive measures to reduce pockets of crimes, it's not an entirely security method to forstall a full security protection in a community. If there's heavy security attack, those gates will have little or no effect to stop those attacks. Those gated communities kind of pattern worked in the 18th and the 17th century, but with modern warfare, it is practically impossible for you to stop an attack from an opponent with just barricading your residential area.
There are merits to a gated community scenario in terms of every day crime prevention.
If it is done right with security attackers, thieves will be more inclined to try somewhere
easier because I imagine the vast majority would attack based on opportunities and risk
assesment. If its solely to prevent attack in a time of war its hard to see how a gated
community can withstand a tank attack or artillery but I'm not sure what exactly the OP
is trying to prevent?
