In Chapter 15, Dickens includes an excerpt wherein his characters make paradoxical statements about the British aristocracy. These statements are intended by Dickens as a vessel for satire, as seen in the passage below:
'There's something in his appearance quite—dear, dear, what's that word again?'
'What word?' inquired Mr. Lillyvick.
'Why—dear me, how stupid I am,' replied Miss Petowker, hesitating. 'What do you call it, when Lords break off doorknockers and beat policemen, and play at coaches with other people's money, and all that sort of thing?'
'Aristocratic?' suggested the collector.
'Ah! aristocratic,' replied Miss Petowker; 'something very aristocratic about him, isn't there?'
One tends to associate the word "aristocracy" with dignity, power, or refinement. It appears odd, at first, to call a Lord who "break[s] off doorknockers and beat[s] policemen" and gambles others' money away "aristocratic." Dickens is, in fact, using this unexpected word choice to satirize and comment on the exploitative, undignified behavior of many people in power. Aristocrats do not earn their titles and power, but rather inherit them. As such, they often use their wealth and resources to support irresponsible behavior, so habituated to these privileges as a given that they are willing to "play at coaches with other people's money" without a second thought.
