Plus our NI isn't just for pensions.
We all end up paying for stuff that seems unfair, most of my working life I was paying for the loans for reparations to slave owners, bad for me even worse for my husband who is the descendant of slaves, what a slap in the face for him to be funding the reparations.
WWII loans were also being paid for a large part of my working life, I wasn't alive in WWII.
I used to know the dates when those loans stopped but I can't remember them now.
Sometimes things seem odd, sometimes they seem unfair. Not alot we can do about it really.
