I started work just after the Equal Pay Act had been passed, and went into the civil service. I discovered that the boys who joined at the same time, with the same qualifications and on the same grade were given a different job title, and were expected to go on day release to work towards promotion to management grades. Most of them did, whilst the girls stayed in the office and didn't progress beyond supervisory grades pretty much based on length of service. In the 'men's' office 'girly' calendars were commonplace. Not exactly pornographic, but topless and deeply embarrassing to teenage girls who already had to run the gamut of coarse remarks when we went in there to get instructions from the men and boys. In the 'female' office, the only men were the bosses who had private offices at either end, whilst we were in an open plan one that stretched between them.
I left, and ended up going into teaching in HE, where at first, like most people entering HE, I was on short-term and sometimes hourly paid contracts. Back then, this meant that I couldn't join the occupational pension scheme, although I have paid NI for all of my working life of over 40 years. Private pensions did exist, but were far less common than now, and as my income was sporadic and insecure, we had young children, and I was worried that I wouldn't be able to pay for some months of the year, I didn't get an occupational pension until I got a permanent full-time contract at the age of 40. I regret that now, particularly as women who opted not to work when their children were born got NI contributions made for them, in some cases for decades, as they used to be paid until the youngest child was 16. As has been pointed out, those of us who did work often brought up children as well as working, not instead of, and the fact that in many cases it is women who could not afford not to work who have subsidised the pensions of those who could, is (IMO) blatantly unfair.
The vast majority of men in HE have full pensions, and as they are still final salary ones, their higher salaries combine with this to make them significantly better off.
Even in HE, which can seem to be an inclusive environment, the gender pay gap in the place I worked was over 20%. Most people are paid on a scale, so discrimination is not overt, but there are far more men than women on higher level contracts which are negotiated (Vice Chancellors can easily earn hundreds of thousands a year, for instance), and the majority of people on fractional or insecure contracts are still women.
I see feminism as still very important. To me, it is about ensuring that there is fairness at all stages of life, and in all areas. I'm not arguing that only women should get 'time off' for children-related issues, but that parents should be able to respond to crises with children (or elderly parents/sick partners etc). Similarly, caring roles should not be assumed to be 'female' ones, and more men should be encouraged to take part-time contracts at work - whether because of family commitments or to pursue other interests if they can afford to.
Period poverty, the number of unsuccessful rape cases at one extreme, and things like women being expected to wear heels and make-up at work at the other all point to an ongoing need for feminism. In some ways, women seem to conspire against it, though. How many women do we hear saying that it was their daughter (or DIL) who didn't send a (family) card, or isn't keeping the house clean? How many women insist that they would rather work for a man? Or talk about adult women as 'girls' when they wouldn't refer to adult men as 'boys'?
To answer the question - yes, I think that many of the issues have changed since the 70s, but there is still a long way to go before our daughters genuinely have the same life chances as our sons.
