"I mean, the idea that Bar could have sent him off on a Grand Tour. But he wasn't the least bit interested. Why? Why isn't he interested in the world? Because here's the bad news for him: He's in the world now"

The quote by Chris Matthews recommends a conversation about a person, referred to as "Bar", who had the opportunity to widen their horizons through experiences such as a Grand Trip, which historically refers to an extended cultural trip around Europe that was as soon as popular among young aristocrats. The Grand Trip was meant to cultivate knowledge, experience, and sophistication by exposure to various cultures, histories, and ideas.

In this context, Matthews points out that "he"-- presumably someone more youthful or less knowledgeable-- is withdrawn in engaging with the world despite having the means or opportunity to do so. Matthews appears to critique this disinterest as a concerning trait, indicating that such a lack of curiosity or openness to the more comprehensive world is detrimental.

Matthews then provides this individual's apathy as bothersome, calling it the "bad news" for him, highlighting a paradox: although he may have been indifferent to checking out the world, he now finds himself totally entrenched in it with its intricacies, difficulties, and diversity. This could suggest that the person might be unprepared for the needs and realities of the world due to their previous lack of engagement or exploration.

This interpretation comes up with wider questions about the value of worldly awareness and cultural engagement. It highlights the value of being linked to and comprehending different facets of the world before one is inevitably thrust into it. This disconnect can cause a lack of readiness for the complex nature of modern-day life. Furthermore, it raises questions about privilege and use thereof-- having the methods and chance to discover and grow but choosing not to take advantage of it.

Matthews may be urging readers to recognize the value of nourishing one's point of view through experiences and education, suggesting that to prosper on the planet, one must initially choose to actively engage with it, seriously believe, and appreciate its vastness beyond the boundaries of their immediate environment.
