opulence (adjective)
- affluence, wealthiness
- abundance
In the article “Here, Poverty And Privilege Are Neighbors; Income Gaps Are a Source of Resentment And Guilt” by Janny Scott, the word opulence is used in this sentence: “…an area along the beach in Brooklyn where West End Avenue appears to be a stark line of demarcation between the serene old-immigrant opulence of Manhattan Beach and the teeming new-immigrant enclave of Brighton Beach”. Scott is saying that there is a clear boundary (huge difference) between a peaceful, wealthy neighborhood and a densely populated ethnic enclave.
