Everyone gets affected by changes in government policy. It’s annoying but the consequence of having a ridiculously large population for the size of country we have
To have changes in policy is part isn't the actual problem, it was the way that this has been completed which put some woman at a disadvantage without the ability to make those changes as time had passed.
If you were born in 1954 you would start work on average in 1968, without the ability to have a work pension, without maternity pay and the prospect of being sacked/let go when you got married or pregnant and not being paid the same wage as a male counterpart. All those factors in a job would affect the ability to pay into a pension and make provision. If you returned to work in 1994 at 40 years old you would then have equal pay and the right to have a workplace pension - but by now you'd have to pay much more into a pension at 40 years old to have the same affect as paying into a pension at 20 years old.
To say everyone gets affected by government policy, can you name another policy int he last 100 years that has changed and had so many factors that were affecting a group of people?
