>It’s hard to deal with that when people have been paying into the system for their whole working lives on the promise that they will be looked after in old age.
They weren't paying "into the system". They were being taxed.
Treat it for what it was, and stop feeding the pyramid scheme.
I had a promise that if I paid NI then I would receive the state pension.
It might have been better not to make that promise but you can’t blame people for accepting it.
