Explain why societies can or cannot satisfy all the wants of its people?

??? Your question does not suggest any particular answer.

They cannot, since resources are limited by the laws of the universe, nor is it their intent. Societies allocate the available resources in a manner they deem optimal for a common goal, which the individual would not manage as objectively. Essentially, all they provide is rules. Were resources unlimited & available to all men, society would dissolve, arguably, for lack of utility - that is a theme in various scifi works.
