Trades among nations is desirable because it makes it possible for people in a country to enjoy the goods and services produced in other countries. This can lead to greater variety, lower prices, and higher quality products for consumers. It also encourages specialization and efficiency, as countries can focus on producing the goods and services that they are best at, and trade with other countries for goods and services that they are not as efficient at producing. This can lead to increased productivity and economic growth. Additionally, trade can help build relationships and understanding between countries, as people interact and exchange ideas and cultures through trade.
