Yes, I've seen that statement on feminist lists of how women were/are oppressed. As with most such other things they list, this is very, very misleading.
As others have indicated, nationally recognized credit cards didn't even exist until the late 1950s and then they were very difficult to obtain. The vast majority of people, male or female didn't qualify. Even in the early 1980s, when I was a young adult, I could only get a credit card if my parent's co-signed for it. It's not like now where anyone can get a credit card no matter how bad their credit is.
So yeah, it's true that it was difficult for women to get credit cards then, but what they conveniently omit is it was difficult for men to get them too.
