Really. I don't know when you think modern society arrived or what experience you base your comments on, but what you say may well have been relevant to generations a few decades ago.
Myself and a number of friends, have been in careers longer than you've been alive. My line manager was the first person in the organisation not to have leave employment when she became pregnant.. So for the best part of forty years several of us have worked full time with people of all ages, most of whom were also raising families, through the ever-changing employment practices and rapid social change. Whilst the methods and ideas are obviously different between generations, the role in society does not seem that different to me - working hard and raising the next generation.
My experience is people in their fifties and sixties today are very different to those in the past. We have plenty in common with younger people through music, internet, travelling etc. We have kept up with change, no choice really, and with a bit of luck we may be able to influence current values and attitudes for the better.
My comments are true of any generation. If your boss was the first women not to have to give up work when she got pregnant then presumably in your grandmothers and mothers age it was assumed (and considered desirable?) that women gave up work when they got pregnant. To be honest, the fact that you had a career is probably alien to your grandmother. The change comes with every generation, it's constant.
