When people suggest that the 50’s tended to be good and that certain values played a part of that, they AREN’T claiming the 50’s were perfect or that the vast majority of people held these values.
I can’t count the number of times I’ve heard discussions on TV where the topic was unwed motherhood, and somebody pointed out that in the decades leading up to the 1960’s, an educated, ambitious, and successful African American middle class was developing in many urban areas…and that 2-parent households were a big part of that.
