Synonym discussion
Sense: adjective/1
These four labels all describe people with limited money, but each frames the group differently. 'Lower-class' is the most direct social-rank label and can sound judgemental in modern Taiwan English classrooms, so it tends to appear in academic or historical writing. 'Working-class' is preferred in everyday speech because it focuses on doing wage labour rather than on being at the bottom; many people happily call themselves working-class. 'Blue-collar' is narrower again, picking out manual and factory workers — a blue-collar engineer is fine, but a blue-collar lawyer sounds wrong. 'Low-income' is the most neutral and the term governments use in policy: it measures only money, not status. So in essays about social policy, write 'low-income families'; in stories about workers, 'working-class characters'; reserve 'lower-class' for explicit discussions of the social ladder.
Etymology
The compound dates to the early 1800s in British English, when writers began ranking society into 'upper', 'middle', and 'lower' classes. 'Class' came from Latin 'classis', a Roman word for a citizen division grouped by wealth. The hyphenated adjective form 'lower-class' spread quickly in nineteenth-century social writing, alongside 'middle-class' and 'upper-class'. Today the term still carries some of the moral judgement of that older usage, which is why 'working-class' and 'low-income' have largely replaced it in everyday Taiwan-English teaching materials.
