In this proceeding we explore a pathway to radio-loudness under thehypothesis that retrograde accretion onto giant spinning black holes leads tothe launch of powerful jets, as seen in radio loud QSOs and recently inLAT/Fermi and BAT/Swift Blazars. Counter-rotation of the accretion discrelative to the BH spin is here associated to gas-poor galaxy mergersprogenitors of giant (missing-light) ellipticals. The occurrence of retrogradeaccretion enters as unifying element that may account for theradio-loudness/galaxy morphology dichotomy observed in AGN.
