  The JWST discovery of a number of super-early (redshift $z>10$), blue
galaxies requires these systems to be essentially dust-free in spite of their
large stellar masses. A possible explanation is that dust is evacuated by
radiatively-driven outflows. We test this hypothesis by deriving the Eddington
ratio $\lambda_E=L_{\rm bol}/L_{E}$, where $L_{\rm bol}$ is the bolometric
luminosity produced by star-formation and possible black hole accretion, for
134 galaxies at $6.5< z <16$. We find a strong anti-correlation between
$\lambda_E$ and dust UV optical depth, $\tau_{1500} \propto \lambda_E^{-0.63}$;
also, $\lambda_E$ increases with redshift. We confirm that galaxies exceeding a
specific star formation rate ${\rm sSFR} > 13\, \rm Gyr^{-1}$ develop powerful
outflows clearing the galaxy from its dust. This result is supported by ALMA
dust continuum non-detections in three super-early systems.
