Why do people produce and sell products According to Adam Smith?

According to Adam Smith, people produce and sell products primarily due to the pursuit of self-interest, which drives economic activity. In his view, when individuals seek to improve their own conditions, they inadvertently contribute to the overall wealth and efficiency of society. This process is facilitated by the "invisible hand" of the market, where personal ambitions align with societal benefits, leading to a more productive economy. Ultimately, this interplay fosters competition and innovation, benefiting consumers and producers alike.
