Final answer:
The extreme result of unregulated free-market capitalism is referred to as laissez-faire economics, which can lead to negative outcomes like monopolies and poor consumer protections, necessitating government intervention and regulation to maintain a balanced economy.
Step-by-step explanation:
An extreme result of free-market capitalism without government regulation is often referred to as laissez-faire economics. This economic system promotes that markets operate most effectively and efficiently when free of government intervention, epitomizing the idea of 'let it be economics.' However, history has shown that without regulation, free-market capitalism can lead to negative consequences such as shrinking competition due to mergers, the formation of monopolies, and insufficient consumer protections. Notable responses to these issues include the actions of President Theodore Roosevelt in the early 20th century, who 'busted' unlawful monopolies and instituted government regulations to safeguard fair competition and consumer interests in industries such as railroads and oil, as well as laws to improve working conditions and control prices.
