Cut pensions then. Right now the working are paying full price to the retired. Everyone should get a haircut.
Whether it is representative of the average scheme I have no idea. Anecdotally, my grandfather received a 100% of wage pension from the government after 10 years of service started in his mid 30's (Australia). The expected value of that would far exceed any self contribution scheme, even with tax advantages.
This is why defined benefit pension plans are just too risky for most people. We should shift all retirement plans to defined contribution with individual named accounts. Those are much safer.
