Is there a word for extreme classism?

Is there is a word that describes vehement disdain for people who are perceived to have a lower social status than one's self? I'm looking for a word that is to class-ism as bigotry is to racism.

Solution 1:

I suppose the word that comes closest is snobbery.

Solution 2:

Haughtiness might work.

Haughty (the adjective form) means "having or showing arrogant superiority to and disdain of those one views as unworthy."

Solution 3:

Bigotry is to classism as bigotry is to racism.

That is because bigotry is not a racism-specific word. It originally criticized sanctimonious religious beliefs¹, and subsequently acquired a broader meaning.

Bigotry now refers to “the practice of having very strong and unreasonable opinions, especially about politics, race, or religion, and refusing to consider other people's opinions”.²
