> This is a parody, but not a very gross one. …
So, Orwell wrote the second sentence as a parody of the first sentence, using the modern English that he was criticizing in the essay.
> … in the middle the concrete illustrations – race, battle, bread – dissolve into the vague phrase ‘success or failure in competitive activities’. …
> … The whole tendency of modern prose is away from concreteness. …
> … The second contains not a single fresh, arresting phrase, and in spite of its 90 syllables it gives only a shortened version of the meaning contained in the first.
He tried to argue that the second one is worse, but, unfortunately, he successfully simulated one possible interpretation of the original. Sure, the parody has narrower meaning, but it is a valid subset of the original meaning, which is still very significant tbh. This justifies the reduction of “race, battle, bread” into “success or failure”, invalidating one of his points.
Also, the parody is not necessarily less concrete. It replaced poetic expressions in the original with words that are bloated, for sure, yet more concrete. It does have awkward expressions, but every word plays a role in the sentence. This basically conflicts with one of his criticisms in the essay — meaningless words.
Funnily enough, his another example — “some comfortable English professor defending Russian totalitarianism” — also fails to capture the nature of the modern English. He points out the “euphemism” towards the violence as an issue of style, but, no, that’s the whole purpose of it, and his example really just excel at it. Style-wise, again, the writing is very solid.
All in all, Orwell simply failed to properly simulate what he was trying to criticize. Good examples of “modern English” can be found in the earlier part of the essay, basically written by other people. Those examples do fit into Orwell’s criticisms.
