Low class is a derogatory term that describes individuals or groups who are considered inferior or of lesser value than others. There are several synonyms that can be used in place of the term low class. Some of these include: lower class, belonging to the lower strata, working class, proletarian, blue-collar, ne'er-do-well, bum, hooligan, lout, and scum. While some of these terms may seem harsh, it's important to remember that nobody is inherently low class based on their social standing or economic situation. It's important to treat all individuals with dignity and respect, regardless of their perceived status.
