I really cannot understand how the right still believe state pensions are a benefit. The anount you receive is not universal (everyone gets paid the same) but is based on how many years of contributions each individual has made.
If you save in a private scheme and draw a pension you are not receiving a benefit. State pensions are just the same.
There will always be those who believe anything ‘public’ is evil while anything ‘private’ is fine. Such a belief is irrational; there is good and bad in both. Neither are perfect.
