use today's glut of savings to finance a surge in public investment. That might be partly linked to a shift to lower-carbon growth.

-- lines up nicely with what afew wrote above:

There is expansion in creating the conditions for reduced (finite) resource use, ie creating infrastructure for the energy transition, building new and refitting old constructions to be as energy-neutral as possible, transforming agriculture  from its current trend of rapid destruction of soil fertility and water to practices that actively foster those resources (yes, there is a gain to be had there).

unless I read Wolf and/or afew incorrectly.
