I think you are right that we have not unilaterally progressed in terms of equitability since 1970, but by my understanding of history the upward mobility you describe would be much more accessible to a woman or non-white person in America today than in 1970.

But not every American, not by a long shot (not to say that today everyone has equal opportunities across gender and racial demographics, but we've improved).
