Thousands of people took to the streets of Buenos Aires, Argentina, on Wednesday to protest against the government's economic shock measures, in the first real test for Argentina's new libertarian president, Javier Milei. Milei, who took office earlier this month on a promise to slash public spending, has announced sweeping plans to reform the economy and crack down on protests in recent days, setting up a potential clash with social groups that have pledged to oppose his "shock therapy."
