There are changes to the tax and benefits system all the time, often at no - or only a few months - notice. Just in the last few years we've had the 2 child benefit cap introduced, the removal of child benefit for higher earners, the removal of the winter fuel allowance, the changing terms on student loans (& the massive increase in tuition fees), the increase of the school leaving age to 18, council tax surcharges... and on and on. There are losers in all these policies, but they don't get compensation. This is the price of being a society.
There is a safety net for the poor and sick: the means tested benefit system. Yes, it's not a lot, but it is there. The idea that the WASPI women get nothing and those that came just a few years later are much better off is wrong.
And the notion put forward by some on this thread that WASPI women were all trail-blazing feminists who set up the benefits women enjoy today is also wrong. Women born in the 60s, 70s, 80s, 90s..... have all had their battles and setbacks to fight and overcome. We are all building on the advances of previous generations. The WASPI women aren't any different - or anything special.
Finally, there are still benefits that people get from the age of 60 - including the WASPI women: free prescriptions, free eye tests, free public transport (in London), discounted leisure activities (railcard, tickets etc) and so on. And those WASPI women who retired early and took their occupational pensions (like that ridiculous headteacher who seemed to be the figurehead for the WASPI campaign) benefited from not paying national insurance on their pension income - unlike their peers who were still working.
All the money the WASPI women have spent on this campaign and all their legal costs would have been much better directed into a charity fund to help those in need not covered by, or to top up, the social security system.
I do think they have been led up the garden path by the Labour govt - but so have students who were promised by Keir Starmer in the past that Labour would get rid of tuition fees.
