Let me relate a true story, and then discuss some implications. After dinner one night, many years ago, an Indian co-worker and I started discussing politics. The Indian wanted to know why we didn’t nuke Pakistan in our hunt for bin Laden. I said that the fallout would kill tens, if not hundreds, of thousands of his countrymen. His response? “They’re excess people.”
If you don’t care about others, then you will use the “other” for your benefit - not mutual benefit. You will be used, you will be lied to, and the political maneuvering will be slanted against you.
Note that this isn’t limited to Indians. It’s, unfortunately, becoming more prevelant in American society, too. In a shrinking world, tribalism (aka identity politics) will be an increasing problem. But Indians have been practicing it for 6K years, so they’re especially good at it.
