I will assist my neighbors as best I can, well at least most of them.
We have one set that is absolutely no use to society and would turn into a liability with a quickness, so they are on their own, but the rest of us would absolutely band together, secure our immediate interests, then branch out to assist the close surrounding area (if necessary).
We have discussed it, and have a loose game plan in place; as well as, individual emergency kits for our own preservation.
We still differ on the BUG OUT plans...but to each his own.
We HAVE been blasted with several hurricanes in the last few years, and we saw no real issues aside from
- cheating contractors being paid by the government to install tarps on damaged roofs, who decided to install them and be paid for roofs that did not need them.
- morally corrupt individuals going into the food lines for MRE's and ice, even though they had electricity, water and plenty of food.
I had one guy come on my property offering the goods to me, but ran him off with a quickness.
For the most part everyone behaved and was completely civil.
The entitlement crown did exactly as expected...they sat on their asses cried and whined expecting somebody else to do all the work to put them back into their free housing and reinstall their mailbox so the foodstamps could arrive.
There was a gun shop robbed
during one storm, that was a bit of a surprise, but that's the only idiot incident that is fresh in my mind.
I had one particular neighbor complain about a tree that was blown down and didn't like the way I stacked or the location of the debris pile

They are still complete asses about that, but their behavior is expected; as, they are socialist minded conformists who pretend to be christians once a week with nothing better to do than create problems to keep their minds occupied as they wait for the inevitable end all humans face.
I'd like to say I can completely trust my immediate neighborhood, but there are new people coming into the area all the time, and I cannot be certain that they won't panic and try to take what they think they need.
I hope I never need to find out.
With the cost of everything as high as it is and climbing, having rotation of supplies is becoming increasingly difficult to maintain.
I can imagine that there are many forsaking the need to restock because it is quite simply cost prohibitive to do so in some cases.
