Why do you think there should be equitable distribution of resources? What forces would be working against an equitable distribution of our resources?
The resources of Earth must be equally distributed among all people, whether rich or poor. None should be deprived of these resources. Every individual should be benefitted and must get equal rights to access the available resources. Such an equitable distribution of resources helps to reduce over-exploitation, wastage and misuse of these resources.
Corruption, greed, over-consumption of resources by the rich and powerful society of people, the difference between rich and poor and the profit gained by exploiting these resources are the forces that would work against an even distribution of resources.
