Women can, do, and always have looked after their own well-being when they could, but the fact remains that the law was stacked against women for years, and it is this, IMO which made it fair that women got state pensions earlier than men.
Women were not always allowed to join in occupational pensions. Until the EA, women and men were paid different rates for the same jobs, and for years afterwards it was easy to employ women and girls in jobs with different titles to mean and boys so they still earned less. Many women gave up work to look after children. Working part-time meant that many were excluded from occupational pensions for years, so their contributions were lower on retirement. The law allowed women to pay in less (the married women's stamp) which meant that they had smaller pensions - it goes on and on.
Yes, men have grievances too. Let them fight for them, and there is a good chance that I will support them. But those grievances are not what women are talking about. And critically, it is not the 'equalising' of the SPA that WASPI is about, (although other women's groups are fighting for recognition of the inequality that led to the differential in SPA to be recognised - as I keep saying, WASPI is only one pressure group amongst many. It is the lack of notice given to so many women, who were left with insufficient time to get their affairs in order and plug the gaps that suddenly opened up before them.
