Tude, you helped me to revisit the lone-wolf survivalist approach. I find when a community comes together, beautiful things happen and the standard of living increases. Being part of a collective whole has safety and insurance benefits, but that doesn't say individuals have to adhere to this survival scheme to be successful. Unless you're completely confrontational warrior blood Rambo lifestyle man, I think you'll find man has a greater chance of survival when he is part of a gang. The quote 'you scratch my back and I'll scratch yours', and the phrases 'I got your back' and 'cover me' come to mind.
In a group each unit has a responsibility to contribute to the group. Artists, scientists, doctors, priests, soldiers, chefs, they all have an uncommon specialty to offer. People often times work alone, but their end result benefits the whole. Not many people could spend 4 years painting a beautiful masterpiece on a church ceiling. Michelangelo shared himself with us and we thank him for that. Does the invention of the helicopter not offer some usefulness to society? The cultures we're immersed in provide so much for us, but it only progressed this way because people gave back.
