Overall, yes, I think it's better insofar as things have improved for women in broader terms- e.g.: females performing better at A level and university, having higher aspirations for themselves etc. I also wonder whether shared parental leave will make a difference, because if mothers start to transfer some leave over to the father it creates more of a balance from the early days of parenting, so it won't by default be the woman who takes a greater career hit. However, takeup of it has been disappointingly low so far. (I realise there may be financial implications if the man is the higher earner, but if couples are serious about sharing responsibilities then they may consider taking the short term financial hit, just as many WOHP do with childcare costs) I think shared parental leave is a wonderful piece of legislation- I only wish it had been around 20 years ago! All these things bolster womens' rights and opportunities and therefore should have a knock on effect in improving their position financially. Also the changes in legislation about employers and automatic enrolment in pension schemes have highlighted the fact that people need to make provision
However, all that aside, the evidence is that a frightening percentage of women remain unprepared for how they will support themselves in their older age, particularly if they outlive their husband. (The percentage of men with inadequate provision is also a concern, but it's significantly higher for women.)
I think a major reason is that to get the maximum gains from any provision you need to start young- and many people understandably don't think about their retirement when they're in their 20s and 30s
It's also very easy to fall into a working pattern for various reasons, and once in an established pattern it can be difficult to change. I consider myself reasonably intelligent and aware, but as I've already mentioned, there was an element of luck in that a full time post in my subject at a local school cropped up at exactly the time my youngest turned 4 and started school. I had been doing a 3 day a week job share while the children were pre schoolers, and TBH if I'd continued doing that for another year while my children were in school, I'd probably have slipped into a pattern of using my newly acquired 2 child-free days to do housework, shopping, school prep and marking... then I would have started to feel i needed that time for those things (because jobs can easily expand to fit the time available) and who knows, I could still be doing that now. I have several teacher colleagues of a similar age to me who have worked part time most of their career and it's only dawning on them now that their pensions are severely depleted. I don't know about all public sector pensions but I imagine they're similar in that even having a few years knocked off your pension affects it disproportionately. And these are intelligent, educated women, so Its not about people being stupid- it's a more complex set of reasons that have resulted in women being disadvantaged.
So- long post! But overall yes things have improved. But not enough to address the scale of the problem, particularly with people living longer. I think the pensions crisis over the next few decades is going to be a massive issue.
