No one will help you out, all this brotherhood crap is for the birds. At the end of the day self preservation always win and you will be sold down the river. Take care of yourself and your family and leave the rest to struggle.
I wouldn't leave myself in dire straits by giving away the last bit of ammo I had, but I definitely disagree that you can't count on having the right friends available when you someday need them. Friendships are a give and take. Although I have a lot of acquaintances, I also have a handful of really close friends that I know I could count on if I really needed something. Similarly, they can count on me!
As an example, I gave one friend a couple of magazines and 100 rounds of ammo when he bought a gun for which he could find none at the peak of the pandemic nonsense. But, this friend has also spent plenty of time using his expertise to help me fix my truck, repair problems around the house, or dog sit for me when I'm out of town. He's there when I need him, and I'm there when he needs me.
Another friend just spent the day helping me move 25,000 pounds of fill dirt at my house. He has also driven across town on a moment's notice when I've needed his help with other issues in the past. I've given him some ammo in the past. It's a give and take... sometimes I'm the one in the position to give, sometimes the opposite is true.
Another good friend was my partner at work for many years, I've known him longer than my wife, and we have been shooting buddies for 15+ years now. If he needs some ammo, I'll help him out, and I know he'd do the same for me.
Then we get into the issue of some lifelong friends... guys I've known since I was 3-5 years old. Some of them are just like family. If I needed it they'd give me a whole gun and ammo. I'd do the same for them.
But, yeah, if a "friend" is really just a mooch pretending to be a friend, then they can fend for themselves.
