Though, perhaps, slightly Randian, this article touches upon the inherent hierarchal nature of people, and, paradoxically, the pursuit of total equality will always lead to another ranking system, replacing it with an inferior measure, of which will be, in fact, less fair, and more crude.
Striking a much different tone from the previous article, with a much more liberal slant, it states: that yes, we can somewhat remedy inequalities, but we can never get rid of them, as inequality is an immutable property of groups and cannot be changed.
In our current system of capitalism, by the very nature of it, makes true equality impossible, due to the ability to gain and lose wealth, this naturally will create inequalities, so in our, and most other countries in the world equality is already impossible.
The most famous quote from Animal Farm, and further reiterates the aforementioned failure of ultimate equality (and in a more narrow sense, communism).
Though I've said why equality is impossible under capitalism, even under communism, it is impossible. The brilliant novella, Animal Farm, by famed political satirist, George Orwell, further describes and emphasizes this point that hierarchies are inherent to groups, where even in societies whose sole purpose is to demolish this hierarchy it still culminates.
This song, as you may imagine, is about equality, and it is awful. This is not just because the Red Hot Chili Peppers are a bad band, rather, this song represents a severe naivete and our tendency to repeat banalities regarding said issue, and have a very shallow, unnuanced view on equality.
