  Observations of radio loud active galaxies in the XMM-Newton archive by
Mehdipour & Costantini show a strong anti-correlation between the column
density of the ionized wind and the radio loudness parameter, providing
evidence that jets may thrive in thin disks. This is in contrast with decades
of analytic and numerical work suggesting jet formation is contingent on the
presence of an inner, geometrically thick disk structure, which serves to both
collimate and accelerate the jet. Thick disks emerge in radiatively inefficient
disks which are associated with sub-Eddington as well as super-Eddington
accretion regimes yet we show that the inverse correlation between winds and
jets survives where it should not, namely in a luminosity regime normally
attributed to radio quiet active galaxies which are modeled with thin disks.
This along with other lines of evidence argues against thick disks as the
foundation behind the radio loud/radio quiet dichotomy, opening up the
possibility that jetted versus non jetted black holes may be understood within
the context of radiatively efficient thin disk accretion.
