Money, Financial Markets and Economic Growth
Money is anything generally accepted as payment - it makes trading infinitely easier than bartering your geography textbook for lunch. Interest rates are the price of borrowing money and the reward for saving it, affecting how much people spend versus save.
The financial sector includes the Bank of England (which controls monetary policy), commercial banks (where you have your account), building societies (focused on mortgages), and insurance companies. They provide crucial services like credit, liquidity, and risk management.
Economic growth is the percentage increase in GDP - basically how much more stuff a country produces each year. It's brilliant for raising living standards and reducing poverty, but it can cause environmental damage and inflation if it grows too fast.
Unemployment happens when people want jobs but can't find them. There are different types: frictional (between jobs), seasonal (Christmas temp workers), structural (industries dying out), and cyclical (economic downturns).
Key Insight: The financial system is like the circulatory system of the economy - when it works well, money flows smoothly to where it's needed, but when it breaks down, everything suffers.
