I think that's what yastreb is saying, you can talk sense to peasants or proletarians much more easily than to people who come from a petite bourgeois or privileged background.

idk what the excuse is

They don't want to know the truth because it will cause them severe cognitive dissonance to understand that their privileged position is based on the exploitation of others, it's better for them to be a left liberal who thinks that they're the good guy etc
