"Getting Depressed About U.S. Success"

Excellent. "I've learned that there's a cloud in every American economic advantage."

Being optimistic about the U.S., as I have learned, means you are naïve, simple-minded, even deluded. Being pessimistic means you're worldly, seasoned, even downright smart. Nobody can put anything over on a pessimist. Just ask all those people who sold their stock when the financial crisis hit. They understood that the U.S. would never come back. And, for them, it never did.
