I saw the most changes in the 1960s. Even with "the pill" not all young women were into promiscuous sex or the infamous one-night-stand. But you know that already. We still feared disease and many young men still saw girls who slept around as loose and as pigs and ######s. So there was our reputation to worry about. There was still that double standard.
Elle, that double standard still existed to some extent in the 1970s when I was again single. Not that men expected us to still be virgins in our 30s - they did accept women having sex in long term relationships, but those who "slept around" as they called it, were still looked down on and got little respect. They were the ones who were used-and-abused as some of us viewed them. The men didn't seek serious relationships with them, some crudely calling them open sewers. IOW, slam-bam-thank-you-mam and they never looked back. Now that went both ways with those I hung around with because there were men who slept with anything still breathing, loving those "open sewers." Wallowing in one after another.
None of us with any self respect, knowing the guy was a p---- man, would get involved. I personally avoided them.
As for salaries. I agree. No one I knew worked in the early 60s, being home with kids. That is except those who chose not to have children. We all went to work when the kids started school, finding anyone we could to babysit. Salaries were low for us because we hadn't worked in years and most didn't have marketable skills being HS grads only. Those who quit got their GEDs as I did, but that was little help getting a decent job.
