What did Donald Trump do today?

He got "mentored" in economics.

Argentine president Javier Milei today became the first foreign leader to meet with Trump since his re-election. A self-described libertarian, Milei has decimated the workforce of the Argentinian government—something that Trump has promised to do in the United States.

Milei has a lot to gain from the support of an American president, and has in the past week tried to position himself as a sort of economic mentor for Trump.

Trump, who is notoriously susceptible to flattery and manipulation by world leaders, appears to have been convinced. He called Milei his "favorite president" yesterday and cited what he apparently thought were Milei's economic accomplishments.

Since Milei took office, annual inflation has spiked into the 200-300% range. The number of Argentinians living in poverty has gone up 36%.

Why does this matter?

• Presidents should get their economic advice from actual U.S. government experts, not foreign leaders with their own agenda.
