Ariel Zilber, Theo Wayt, and Bruce Golding write for the New York Post about an interesting war of words between the president and a billionaire.

Who are you gonna believe: the world’s richest man or the president with plunging poll numbers?

Billionaire Elon Musk has such a “super bad feeling” about the U.S, economy under President Biden that he plans to lay off about 10% of the workers at his Tesla electric car company, it emerged Friday.

Biden reacted to the tech mogul’s gloomy outlook with sarcasm — and then took a jab at his SpaceX company’s upcoming mission.

“Lots of luck on his trip to the moon,” Biden said of Musk during an extended weekend trip to his Delaware beach home.

Musk snarked back on Twitter with a link to a 2021 NASA press release about SpaceX winning a $2.89 billion contract to send the next American astronauts to the moon in preparation for an eventual trip to Mars, where Musk plans to establish a human colony.

“Thanks Mr President!” he added.

The war of words erupted against the backdrop of Musk’s new status as the No. 1 enemy of progressives, who are infuriated that he plans to buy Twitter and turn it into a platform for unregulated free speech, which proponents say would give conservative viewpoints a footing on the liberal-dominated social media site.

On April 15, Sen. Elizabeth Warren (D-Massachusetts) sarcastically wished Musk a “Happy Tax Day,” noting that he reportedly paid no federal income tax in 2018 — even though he said he’d pay a record $11 billion on his 2021 earnings.

Rep. Alexandria Ocasio-Cortez (D-NY) has also accused Musk of having “an ego problem” and last week told Bloomberg she wanted to ditch her Tesla Model 3 for an electric vehicle made by unionized workers.

Musk is an outspoken opponent of unions who recently tweeted that he planned to stop voting for Democrats “because they have become the party of division & hate, so I can no longer support them and will vote Republican.”
