The resources needed to satisfy all the want of human being are said not to be enough compared to all the want of humans we have many want we would like to satisfy at any given point in time which we may not be able to meet up with due to economic problems scales of preference simple is setting our needs inorder of priority.
Human needs always increase every generation as well as the preferences of each generation have an orientation in life so that it will form a new idea to fulfill their preferences if no one offers it to them, if you compare human desires and their resources I think it will never be enough at any time basically humans are never satisfied even though their wishes have been achieved, there is always a position where they think of new things and want new things that are increasingly trendy or more prestigious, I really agree that indeed resources will never be enough to fulfill every desire even if you have have what is in this world, impossible things will definitely be your desire.
