Collusion is when two or more parties secretly work together to achieve a common goal, often in a way that is dishonest or illegal. For example, in business, companies might collude to fix prices, which means they agree to sell their products at the same high price instead of competing fairly. This can harm consumers by limiting their choices and keeping prices high. In politics, collusion can occur when individuals or groups conspire to influence an election or manipulate public opinion. A well-known example is the 2016 U.S. Presidential Election, where allegations of collusion between political campaigns and foreign entities raised concerns about the integrity of the democratic process.
