In the article “Here, poverty and privilege are neighbors; income gaps are a source of resentment and guilt” on page 5/7 2nd paragraph the author states “Professionals, predominate; most Manhattan Beach adults have college degrees ”
The author used predominate in this sentence to make it clearer to the reader that this class of people own certain stuff and shows the difference between others who don’t have as much money or” power “.
