So then, a dilemma rose in the mind that, if I'm also an exploiter, then this is not right

But it appeared to me that all these years that I'd been working on exploitation exploitation by landlords, by moneylenders, by traders gave me an insight that probably I was also an exploiter, because there was no line in my income tax return which showed this income accrued because of the brilliance of the people those people who have shared their knowledge and good faith and trust with me and nothing ever went back to them.
