Subjunctive or No Subjunctive?

The question of whether or not the subjunctive is necessary in the English language is one of personal choice. We clearly see that the subjunctive's use is fading out in schools, but is this fading out just?


When comparing sentences of "If I were a rich man," and "If I was a rich man," the use of was implies more of a past tense form of the verb is, but were is just as useful, if not more so because of its versatility. 


The problem here is that most people treat this option as they treat an Oxford comma, where it is only slightly more useful. It is for this reason that it is fading out in our English speaking world. In other languages, the subjunctive may be vital to the understanding of the sentence, but in English, the subjunctive combined with the multiple uses of some of the tenses of many verbs creates redundancies that are almost best avoided by using the more common tense of the word, even if it is not as good as the subjunctive tense of the word.
