Yes, that would be true on humanistic grounds. The progressive assumption, though, is that there's a dominant class that resists reform. And indeed, white males arguably still rule in American political and corporate circles. In that context of a lack of perfectly equal outcomes, a progressive would emphasize the need for more attention to be paid to the minorities.

And you haven't shown that my statement is false. What you're saying is that it's not the whole truth. But an author is allowed to emphasize things to support a thesis and to stay true to his or her perspective.
