It is in fact mor inate then you may imagine, look at out closest relations in primates, they compete to become heigher in the social ladder as sucsess and power attracta the females. Humans still poses these desires, granted we are no longer in caves or on the savanah being eten by big cats and so ite less relivent to the sucess of humas and reproduction BUT our minds are loaded with our primal instincts that cannot help but express themselves in the modern world. This i belive is a prime example.
