sir, i bow to your wisdom. the problem is definitely selfishness. lets imagine a society where everyone is given equal share of all resources but they also have to put in equal amount of work based on the individual capabilities, soon enough some members of this society would start seeking ways of not contributing to the work that keeps the resources of the society, but they would still want the resources to be shared equal or even demand greater share. that is where everything crumbles.

I agree perfectly with you. The situation is made worse because we also do not have the same potential. Conversely, even when we all each choose to put in the same amount of work, some of us will have a higher efficiency due to their differential potential than others leading to these having more than others AND couple with the behaviour called selfishness, the rest can just be imagined

But then, youve not anwered these questions
1. Why are human beings basically selfish?
2. Is there any solution to this problem?
3. Can selfishness be quantified?
