Mr Hutton may face the difficult task of pushing forward legislation delaying the official retirement age or introducing compulsorysaving for pensions.
The problem with setting a higher compulsory level of saving is that it would be unpopular - many would see it as a tax - and inappropriate for certain categories of people.
These included increasing the basic state pension in line with earnings, basing eligibility for the state pension on residency, introducing a universal pension for the over-75s and creating a National Pensions Saving Scheme with compulsory employer contributions.
These harmful side-effects might be tolerable if compulsory savings served to boost national saving, and if this led to higher investment and faster growth.
