The answer is the last sentence you have marked. The last sentence shows how the Prince ignored the chaos that was occurring outside of his land and instead threw a party for the wealthy and powerful. This sentence shows the ignorance of the rich. Hope that helps :))
The irony which was implied in the last line was that the servants in the homes of wealthy Londoners consider themselves to be better than everyone else. As well as their employers, they acted quite arrogant and that is why the narrator said 'the tribe'- because people blinded with wealth form their own unwritten laws that are quoted in their own world where they are the only ones to respect.
Hopefully it's correct and will help you
