Atilla the Hun didn't had any elephants, you are talking about Hannibal who lived few century earlier.

A note about living like the have-nots:

Generators can be heard from far away and will be a dead giveaway. Solar panels on the roof or a wind generator in the back yard can be seen from far away and will also be a dead giveaway.

On the other hand, when you get out into the small towns and countryside, poor folks are just as likely as the well-to-do to have woodstoves in their homes; maybe even more likely. There are plenty of poor salt-of-the-earth types that have always gone out into the nearby forests with a chain saw and loaded up their beat up old pickup trucks with firewood, to be piled outside their beat up old houses. Smoke coming out of the chimney of a house that is not obviously the house of a well-to-do person might be visible from far away, but does not convey the same sort of message as the above examples do.

Eric: You might be right, but the gated communities I have seen in Florida have armed guards.

And if we are at the point where there is to be 'raids' on gated communities, one has to keep in mind the difference between the old and new gated city model.

There was not .308 or .50 cal rifles. The attackers can reach out and touch someone from a long distance. Do these guards want to work when they would lack the 'protection of the state' if they start getting snipped from other urban cover?

And some of the 'members of the lower class' are being trained on how to do this under the idea that the training will result in a chance to move up the ladder.

(Again, - how does this all end well? As a species, we'd better hope that the optimists turn out right.)
