Money operates as a medium of exchange by negating the need for a double coincidence of wants. In a 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.
You see, at the start of most election campaigns, there is one party in the lead and another behind. Today, Keir Starmer fits the role of the front runner, and as a consequence he wants as few debates as feasible (that is, something close to but not zero to avoid accusations he is running scared). Meanwhile, Rishi Sunak trails by 20 points, so he would ideally like as many debates as possible.
