Free trade is an economic policy that allows countries to exchange goods and services without tariffs, quotas, or other restrictions. This means that businesses can sell their products in foreign markets without facing additional costs, making it easier for consumers to access a wider variety of goods at lower prices. Supporters of free trade argue that it promotes economic growth, increases competition, and encourages innovation. However, critics point out that it can lead to job losses in certain industries and may harm local businesses that cannot compete with larger international companies.
