“I see an opportunity for it to become the most pet-friendly city in the region,” Ferrario said.Other politicians fret about the proliferation of pet-keeping as a symptom of a bigger crisis. They ask why young people in Argentina choose raising pets over raising children as the country ages rapidly.“The rankings (of pet ownership) are unsettling. ... Buenos Aires has so many dogs and so few children,” said Clara Muzzio, the city’s conservative deputy mayor. “A world with fewer children is a worse world.”

Perhaps Argentina’s most prominent dog fanatic is its right-wing, who moved into the government house in December 2023 with four English mastiffs that he calls his “four-legged children.”

There are several Trump could use, including Section 301 of the 1974 Trade Act, but that does require an investigation of another country’s trade practices to establish that they either violated a trade agreement or engaged in unfair trade practices.Another possibility is Section 338 of the Trade Act of 1930, which allows tariffs of up to 50% for countries that have discriminated against U.S. imports. It doesn’t require a government agency to investigate anything. And Section 201 of the 1974 Trade Act allows duties to be imposed of up to 50%, but only after an investigation that establishes that imports have harmed a specific U.S. industry. That law was used to slap tariffs on some solar products in 2018.

If the courts uphold Wednesday’s ruling and the import taxes are struck down, the money will be refunded back to the U.S. companies that paid it.Otherwise, it goes to the U.S. Treasury, like personal and corporate income taxes, to pay for government expenses. Tariff revenue collections have spiked in recent months, and were on track to reach about $22 billion in May. That is up from $6 billion in February, before most tariffs were imposed. Economists at Nomura Securities estimate that the tariffs struck down by the court have raised a total of about $40 billion to $60 billion so far.
