In "The Canterville Ghost," how does Oscar Wilde show the class disparity between the Americans and the English?

In "The Canterville Ghost," Wilde demonstrates the class disparity most clearly in the opening paragraphs. Through the character of Lord Canterville, for instance, Wilde depicts the English as keen to protect their traditions and heritage. This idea extends to his view of the ghost:

Lord Canterville himself, who was a man of the most punctilious honour, had felt it his duty to mention the fact to Mr. Otis.

Moreover, lineage is also a point of importance to the English and this is supported by the number of times that Lord Canterville mentions his family:

• We have not cared to live in this place ourselves…since my grand-aunt, the Dowager Duchess of Bolton…


• It…always makes an appearance before the death of any member of our family.

In contrast, the Americans are portrayed as materialistic and modern. They emphasise science over tradition, as seen in Mr Otis's view of the ghost:

I reckon that if there were such a thing as a ghost in Europe, we'd have it at home in a very short time. 

In addition, for Mr Otis, living in Canterville Chase is a status symbol, and not about demonstrating lineage (as it is for the English), and we see this through Mr Otis's emphasis on money:

I will take the furniture and ghost at a valuation.

This disparity between the English and the Americans creates a culture clash (as discussed in the reference link) and this sets the scene for the ensuing conflict between the ghost and the Otis family.
