We know more about the royal families of the UK and Monaco than the names of the rulers of India and China. Even in our own country, the sense of communal responsibility and common good is almost non-existant. Let everyone fend for themselves. The need for patriotism is usually a grouping against a common outside threat. At this time, the US really has no impending threat.
Politicians struggle to create foes.
With no physical threat, people tend to focus on themselves. We look at others as strangers to fear or markets to be exploited. After WWII, the US realized the threat of disease and poverty and invested in the world. It was our greatest moment, and we and the world have reaped immeasurably from it. Today, we ignore the rest of the world.
