Billionaire hedge fund investor Kyle Bass was mocked mercilessly on X, formerly Twitter, after posting an $85 receipt for room service breakfast and tagged Treasury Secretary Janet Yellen and the Federal Reserve.

Bass—who used the hashtags "Biden" and "inflation," which suggest he places the blame for these high prices on President Joe Biden—announced he'd just experienced a "Terrible Inflation milestone."

He added:

"My first $85 breakfast for one at a NYC hotel. After signing this bill, I have decided NEVER AGAIN."

His post, which tags Yellen as well as the Federal Reserve, can be seen below.

Bass has a net worth of roughly $3 billion—and he was immediately mocked for being completely out of touch.

Bass' tone-deaf post brought to mind one from David Brooks last year in which he complained about a $78 meal at Newark Airport.

Brooks was instantly slammed for the tweet, but the difference was that in his mind, it was a joke. Bass is clearly not joking.

Another difference: Brooks expressed regret for his bad tweet.

But the problem with the tweet, which I wrote so stupidly, was it made it seem like I was oblivious to something that is blindingly obvious – that an upper-middle-class journalist having a bourbon at an airport is a lot different from a family living paycheck-to-paycheck. And when I’m getting sticker shock, it’s like an inconvenience. When they’re getting sticker shock, it’s a disaster.

And so, I was insensitive. I screwed up. I should not have written that tweet. I probably should not write any tweets.

As of this writing, Bass has yet to retract or apologize for his post.
