In recent days we’ve been observing how Brazil – which, a few years ago, looked as if it was on the verge of becoming a prosperous, developed First World-style nation – has rapidly declined, during the presidency of Dilma Rousseff, into an economic disaster zone. Meanwhile, the most massive corruption scandal in the country’s history has brought down one member of her administration after another. In the months after her re-election in October 2014, Rousseff dropped from an 80% to an 8% approval rating. Millions are now calling for her impeachment.

Among the most prominent of them is Kim Kataguiri, who turns 20 years old today.

Just over two years ago, when he was an obscure college student, Kataguiri attended a history class in which the teacher attributed Brazil’s economic success – which would soon evaporate into nothingness – to the welfare-state policies pursued by Rousseff and her predecessor (and Workers’ Party colleague) Luíz Inácio Lula da Silva.

“That just seemed wrong,” Kataguiri said in an October 2015 interview with Time Magazine, which named him one of the year’s most influential teenagers. To Kataguiri – a grandson of Japanese immigrants – it was obvious that Brazil’s growth was a result of “the commodities boom and our relationship with China.” In recent years, China had become Brazil’s #1 trading partner, with the value of trade between the two nations climbing from $2 billion in 2000 to $83 billion in 2013.

Kataguiri responded to his teacher’s sunny socialism with a You Tube video in which he spoke up for the free market. The video went viral. He followed it with other videos, in which, as Yahoo News has reported, he and a group of like-minded friends, who call themselves the Free Brazil Movement, “often don wacky costumes and dress up as political figures such as Fidel Castro.”

The Free Brazil Movement’s positions are clear. It calls for the introduction of a free-market system, with lower taxes, a smaller government bureaucracy, and complete privatization of publicly held companies. It also demands the impeachment of Rousseff, whose Workers’ Party Kataguiri (now a college dropout) views as “the nemesis of freedom and democracy.” His heroes? Politicians Ronald Reagan, Winston Churchill, and Margaret Thatcher, and economists Friedrich Hayek, Milton Friedman, and Ludwig von Mises.

As Brazil’s economy faltered, and then, with terrifying rapidly, spiraled down into the dustbin, Kataguiri and his movement became increasingly popular. On March 15 of last year, when over a million Brazilians attended anti-Rousseff rallies, Kataguiri spoke to an audience of 200,000 at a protest in São Paulo.

Pointing out that he had himself “emerged through the Internet,” Kataguiri told Time that he has

a great hope that the internet can have a serious effect on the political world and can bring change. It can improve knowledge, participation and transparency in politics. Now, politics in Brazil looks very bad. Everyone steals. But I have hope that in 20 years things can be different. I have hope that our generation can change the ways things are done.
