By that standard, isn't everything? Aren't all decision, for example, the result of a person's interaction with his or her material surroundings and his or her physical construction?
And whats your point?
Its plain and simple. Should a person be rewarded for coming up with an idea on the basis they were born, or encountered, material circumstances?
If yes, we can justify the rule of monarchs.
Or do ideas come from the persons "greatness" or "intelligence"(on average), whereby we can assert that Africa and its people, with few ideas emerging, are racially inferior. And, infact, Britain, Germany, France and the USA are composed of the "master race" whereby most ideas and inventions we know of today have emerged "simply because of their own genius" (or whatever ridiculous justification is given).
To promote and reward a person for coming up with an idea is to promote the idea of racial subordination and justification enough for the existence of Monarchs.
On the one hand you could justify a persons position based on circumstantial material conditions, on the other, you could deny that ideas are solely due to material interaction and justify racial subordination.
Alternativly, you can accept that a person
should not be rewarded for circumstance and that ideas are the result of material interaction.
