My understanding is that many "blacks" had union jobs, since there was so much more unionization anyway. Employment was better and they shared in that. Not to the extent "whites" did, I'm sure, but better per capita than today.Depends in large part on whether or not minorities, particularly blacks, were allowed to join.
Even so, not being able to use white water fountains, white restrooms, white restaurants, white movie theatres, etc, was a bummer. And there was the whole illegal racial intermarriage thing. And segregated schools.
So was life "better"? Depends on one's viewpoint.
No disagreement re the social issues.
