Demand-pull inflation exists when aggregate demand for a good or service outweigh aggregate supply. It starts with an increase in total consumer demand. Sellers meet such an increase with more supply. But when additional supply is unavailable, sellers raise their prices. That results in demand-pull inflation.
This is commonly described as "too much money chasing too few goods."
The phrase taxation without representation describes a populace that is required to pay taxes to a government authority without having any say in that government's policies. The term has its origin in a slogan of the American colonials against their British rulers: "Taxation without representation is tyranny."
