I don't bother about nomenclature
we can make "despite all the social democratic institutions in the world the number of poor people is decreasing since decades" out of it.
With the video at 8 minutes it illustrated the point that the situation is not so dire and depressing as indicated in your first sentence in your post, rather fewer and fewer people and children are dying early over the past decades.

My main point was that it will be hard to find followers on your way when you name it for-need because a) need is a vague and subjective term and b) it tends to ascetism and only few people like ascetism. Similar it would be difficult if it would be for-wish because wishes are vague and subjective and unlimited.
for-use seems to me equally vague and subjective

as political theory is a broad topic which one could study a lifetime without coming to an end, I see the same problem (hard to find followers on your way) with this:
please educate yourself on the basics of political theory

Imagine: I would come along and ask: What is it what you do, how does it work and how can I get along and you would answer:
First you have to please educate yourself on the basics of political theory and then come back.

I don't think you would find many followers.
