I stumbled upon the article "What happens if bitcoin succeeds?" in which John Danielsson, Director of the Center for Systemic Risk at the London School of Economics, argues that the inequality between rich and poor will be further exacerbated.
Isn't that evident already? While big pocket players are setting up big mining rigs and small players are finding it extremely hard to earn bitcoin. So the inequality between the rich and poor will stay there even in crypto market just the way it happens in the real world economy. There's no way to remove it from our lives!
So I would agree with this statement. Bitcoin didn't help to remove the income inequality from our lives. It certainly made some people richer who had adopted it in its early days but holistically it remained as a big boys' game!
