Final answer:
The free enterprise system is subject to business cycles due to individuals and businesses making economic decisions in their own self-interest, government intervention in decision-making, and minor fluctuations in the stock market.
Step-by-step explanation:
The free enterprise system is subject to business cycles due to several factors. One of the main reasons is individuals and businesses acting in their self-interest make economic decisions. This can lead to periods of rapid growth followed by decline or recession. Another factor is the role of government intervention in making decisions about factors such as prices, production, and consumption. Governments often adjust interest rates and implement regulations to control the risk of economic depression. Additionally, minor fluctuations such as day-to-day fluctuations of the stock market can contribute to the business cycles.
