The infrared and optical spatially extended light from high redshift (z>1) radio galaxies is highly polarized, (up to 40% in K band) and can not be dominated by direct starlight. These objects appear to be giant quasar reflection nebulae rather than ``galaxies''. The extended continuum emission is light from the central regions scattered by dust distributed throughout a 10-30 kpc region. The diverse morphologies (cometary, hourglass, fan, bow-shock) and polarization of these high redshift nebulae are strikingly similar to the appearance of reflection nebulae, jets, and bipolar outflows associated with YSO, although on a vastly larger scale. Based on this similarity and the observed properties of high redshift radio galaxies I propose that the collapse and formation of giant galaxies requires a magnetocentrifugal flow and that disk accretion and bipolar outflow provide the regulating feedback mechanism responsible for the characteristic properties of galaxies. Unique and falsifiable predictions of this hypothesis are discussed in the context of present and future observations of the high redshift universe.
