Around 6 p.m. on July 10th, thousands of demonstrators gathered in front of the São Paulo Museum of Art (MASP) on Avenida Paulista in São Paulo, Brazil, to hold a protest against Trump's imposition of tariffs.

According to Zhongjin, the activists demanded taxing the super-rich, ending the "work six rest one" system, and condemned U.S. President Trump's decision to levy tariffs on Brazil. The protest was jointly led by the Brazilian grassroots organizations "Frente Brasil Popular" (Brazilian Popular Front) and "Povo Sem Medo" (People Without Fear).

In addition to São Paulo, cities such as Brasília, Belo Horizonte, Salvador, Rio de Janeiro, Fortaleza, Curitiba, Maceió, Florianópolis, Vitória, Cuiabá, and São Luís also held demonstrations with the same theme.

In São Paulo, the activists occupied and blocked the two-way road in front of Trianon Park. They also took over parts of the surrounding streets, including the headquarters of the Federation of Industries of the State of São Paulo (FIESP).

During the event, Federal Deputy Guilherme Boulos stated in a media interview that this protest could be considered the largest demonstration of the year. He remarked, "This is an action to defend Brazil from Trump's attacks and also to defend the rights of the Brazilian people."

Boulos emphasized, "Today's event on Avenida Paulista is also a response to those who do not support President Lula's governance. Some people make a fuss when they hear that the super-rich will be taxed in the country, and others disagree with Brazilian workers ending the 'work six rest one' system."

One of the themes of the protest was the taxation of the so-called "BBB." Activists used the acronym "BBB" to refer to banks (banco), sports betting companies (bet), and billionaires (bilionário). According to the organizers, this proposal faces strong resistance in Congress as the vast majority of lawmakers are entrepreneurs or landowners falling within the scope of the new taxation proposal.

Since 2024, a debate has been intensifying in Congress on improving Brazilian working conditions without reducing salaries and ending the "work six rest one" system, driven by the "Life Beyond Work Movement" bill submitted by Federal Deputy Érika Hilton. According to recent data from the Quaest Institute, 70% of lawmakers in Congress oppose changing this work system.

The protest against Trump's imposition of a 50% tariff on Brazilian products was added to the protest themes at the last minute before the event began.

According to data jointly released by the University of São Paulo (USP), the Brazilian Analysis and Planning Center (Cebrap), and the NGO "More in Common," the peak participation during the demonstration was 15,100 people with a margin of error of 12%. This indicates that the actual number of participants in São Paulo's event may have been between 13,300 and 16,900 people.
