“La mia ignoranza interessa più della tua cultura”—Closing line of Wily Wily.
Ghali refers to how much trash and meanness attract more the average Italian with respect to culture and thinking with their own heads, supplanted by an ignorance that is also promoted by the media.
The bar could also mean a contrast between the presumed ignorance of Ghali (or, by extension, of a culture, such as hip hop, still mistreated and debased by the national media) and the equally presumed culture of the average Italian (actually made of widespread ignorance, narrowness and mental closure).

Seems to me it can me used to mean a lot of things.
