If it was Hindi, you would be oppressing the other ~40% of the country that aren't native Hindi speakers and you would be depriving them of the opportunities that English language skills offer to them.
Since it is 'irrelevant', perhaps the colonial state can stop sapping our taxes to fund 'english-only' universities, and instead educate and 'skill' the 90 % (instead of teaching them broken english). It's insane that being pro-British empire is a stance that is even morally justified in a nation of 1 billion.
It's not at all surprising that India's socio-economic indicators are worse even compared to Africa. How would it not be, when the state sucks the blood of the non-elite basically to create an endless supply of white-collar labour for English-speaking nations.

Rather than a 'caste-system', the bigger factor in determining economic success in India is linguistic ability. Even the supreme-courts in India won't hear anything in a language other than English. It's quite insane TBH.
But I'm a brit, maybe an indian would care to opine.

[1] yes, I know
"and is also not subject to the colonial 'english-only' education system that is ravaging India and causing large-scale unemployment."
Why should this be a problem?
