I don't see how anyone could look at the world and believe in karma.

Taking a pretty easy example, I think it's safe to say that most people in the US believe that at least one of Hilary Clinton and Donald Trump is an awful person. Plenty of folks believe both of them are, but I don't think there's anyone who believes neither of them is awful. So surely, karma should impact at least one of them.

But they've both lived utterly charmed and successful lives. Literally the only "negative karma" they've faces is losing a national election (we should all be so lucky to be successful enough in life to be able to lose one), and each has lived to at least 77 years old.

We do see bad people who die young or go broke or whatnot, but that's never karma. If karma were real, it would be consistent, or else at least we wouldn't also see good people dying young and going broke.

At best, we sometimes see justice, but even then, it's brought by men, not by the universe.
