Way back when, we needed to support the development of multi-employer provision, like USS (multi-employer schemes are now the norm in defined contribution), building larger funds with longer-term investment horizons, shifting the balance of power between worker-controlled funds and the asset management industry back in favour of the former. Starting this from where we are now is not ideal, but still a better scenario than the one we are currently facing.
The state could support a new generation of defined benefit schemes by underpinning guaranteed outcomes. As noted above,
the state already offers such guarantees via the Pension Protection Fund, as well as investing many billions in defined benefit schemes via Pensions Tax Relief. If the state is going to be called upon to support private provision anyway, it might as well operate transparently, and used to engineer a more sustainable private sector business model.
And the public guarantee could of course be conditional, with funds expected to invest in, say, the decarbonisation of UK industries and their supply chains. Indeed, once permanence is established, pension funds may be better placed than the state to undertake the gigantic investments now required (i.e. without inducing higher borrowing costs), assuming the state is prepared to mark out the necessary path via public financing.
