No matter what you call it, you simply "CAN'T have what we currently have. In a post SHTF environment you need hard manual labor humans. And they need to physically do their share, plus the share of those who can't do long days of hard manual labor. Or you must dispose of those who reduce the probability of the others surviving.
If a small group was sent to a small community of 500 or 5,000 charged with the job of saving as many as possible. They would likely have to kill at least 20% first thing. Within a few weeks they would need to cull another 10% to 20%.
The reason this subject is timely and interesting for myself, is I very soon "MUST" choose where to move, this will be my last move over which I have some degree of control.
