What does nick mean when he says a sense of fundamental decencies is parcelled out unequally at birth?

When Nick says that a sense of fundamental decencies is "parcelled out unequally at birth," he implies that not everyone is endowed with the same moral compass or ethical instincts. This suggests that people are born into different circumstances that shape their values and behaviors, leading to unequal distributions of empathy, kindness, and integrity. Ultimately, it highlights the inherent inequalities in human nature and social conditions that influence how individuals interact with the world.
