Read the passage. Imagine that a person pays taxes to the government, but has no say in how the government uses the money. This situation is very real for teenagers with jobs. The voting age in the United States is 18, but many teenagers start to work when they are 16. This means some teenagers have to pay taxes but do not have a voice in elections. The voting age should be lowered. As the Founding Fathers said, "No taxation without representation.” What purpose does the juxtaposition serve in the passage? It suggests that teenagers should not pay taxes. It argues that teenagers should earn their money. It explains why teenagers should be allowed to vote. It emphasizes that many teenagers should work harder.
