When you are starving, and the people around you aren't.. and they watch helplessly cuz they don't know how to help you. You feel anger, frustration, resentment, disappointment. They don't know what you need, they don't have it to give it to you. And you feel desperate, so you resent them, looking for something someone to quench your hunger.
There must be a term for this. There is survivor guilt, but what do the people who don't survive feel (assuming they are still alive). Resentment. Abandonment. Because people naturally feel the need to stick together, and people naturally expect that... Except capitalistic society these days, works on the assumption that human beings are selfish, and will automatically pick the individual over the group... and based on society rules, and what we are told, we do exactly that. We look after our own survival, but it's not nearly as simple as that. Our natural human instincts are still there, the anger, resentment, guilt continues to exist. We know in the end, we survive better as a group than alone.
I found this article about Lay-off Survivors. Capitalism continues doing what it does, and the unnatural nature of it leaves us uneasy.
