Actually, this article doesn’t answer the question. It just assumes that ‘income inequality’ is a Bad Thing, and goes from there.
It answered the more limited question ‘why it matters as a political issue‘ by saying ‘it’s getting worse’. No attempt whatever to explain why the author — and, presumably, the intended audience — thinks that ‘income inequality’ is a Bad Thing, just assume that everyone agrees with you and go from there.
That’s ‘journalism’ today.
