OPINION - Rishi Sunak is not six debate zingers away from a surprise victory

Money operates as a medium of exchange by negating the need for a double coincidence of wants. In barter economy, if I have chickens and want to purchase a 30-goal-a-season striker, I am reliant on at least one football club being in need of (let's face it, several billion) chickens. A monetary medium resolves this issue, by satisfying both parties. Incidentally, this goes some way to explaining why the 2010 UK general election was the first to feature television debates.
