We don't capitalize "the rich", but what if the designation is more specific like in the Indian caste system? I've seen Untouchables capitalized. In my novel I have owners, know-profs, labor, and off-griders. In addition there are Founders and Tressers. The latter two I'm capitalizing like one would capitalize Americans and Mexicans. But I'm wavering with the social classes and I'm wondering what other people think. Thanks in advance.
