The quote from "The Little Prince" by Antoine de Saint-Exupéry reflects on how modern life has led to a superficial existence where men lack time to engage meaningfully with the world around them. They focus on acquiring material goods, easily available in shops, which leads to a detachment from deeper human connections necessary for friendship.
This observation suggests that while it is convenient to obtain ready-made products, the absence of effort and investment in building relationships results in loneliness. The inability to 'purchase' friendship highlights the unique and irreplaceable nature of personal bonds that require time, care, and mutual understanding, which are often neglected in pursuit of materialism.
