I prove a formula expressing the descendent genus g Gromov-Witten invariants of a projective variety X in terms of genus 0 invariants of its symmetric product stack Sg+1(X). When X is a point, the latter are structure constants of the symmetric group, and we obtain a new way of calculating the Gromov- Witten invariants of a point.
