I assume what you mean is, if your child is starving and no stores are open... let him die.
You can feed a kid a flat screen tv?
I assume you realize no (American) child is going to die or even be seriously affected by even two or three days without food. Much less missing one or two meals, a far more likely scenario.
Leaving that aside, why in the world would you respond in such a way?
My comment referenced financial and/or recreational incentives, not life-threatening emergencies.
Of course if my family were in dire need of food during an emergency I would forage accordingly.
The difference is that I would forage only for life-sustaining needs and I would keep track of what I took so I could properly reimburse those from whom I took it in future, if it became possible to track them down.
I really don’t think jewelry or an HD TV are needed to sustain life in an emergency. Do you?
