What is Adam smith's idea about the working class?

Adam Smith, often referred to as the father of modern economics, viewed the working class as essential to the economy's functioning. In his seminal work, "The Wealth of Nations," he argued that labor is a key driver of wealth creation and that the division of labor increases productivity. Smith believed that by pursuing their self-interest, workers contribute to the overall prosperity of society, as their efforts lead to innovation and efficiency. However, he also acknowledged the need for fair wages and working conditions to ensure the well-being of laborers.
