The proof of the power of cooperation is in the existence of gregarious insects and sentient mammals.
We humans evolved as a species with speech and by sharing ideas, work and treasure. Our concern for each other should be assumed. We should be the epitome of the gregarious and act as appreciative stewards of the earth.
For each other’s well being to be considered a marketable and individual responsibility is a presumption promoted by sociopaths and accepted by the gullible and meek.
