Here is a quote from Kundera's The Art of the Novel which defines how the dissemination of resentment through mass media works:

"Modern Stupidity means not ignorance but the nonthought of received ideas." (163)

This quote seaks for itself in light of the 24-hour political theater that pits the middle class against the middle class in, for example, the attempt to delegitimize unions and women's reproductive self-determination.
