This year's ball was in Buenas Aires, Argentina.

That it is obscured in other issues demonstrates the depth of the resistant culture in Argentina.

From the story:

The G20 in Buenos Aires: Logbook November 23-25

In the fourth installment of our coverage of the 2018 G20 summit, our correspondents recount clashes over neoliberal assaults on the Argentine education system, the counter-summit of left politicians, and the football riots that forced Senator for Justice and Security of Buenos Aires to resign immediately ahead of the G20 meetings.

Police Attack Student Protests

All week long, there had been protests against a change in the lecturer-training system, which is now to be centralized and controlled by the government. Within this framework, 29 institutes are to be closed; in addition, the previous independence of the lecturer committees is to be virtually abolished. In the future, a government-appointed rector will govern the “UniCABA” (Universidad de la Ciudad Autónoma de Buenos Aires). On top of that, dozens of allegedly “useless” professorships are to be cancelled without replacement.
The comparatively liberal, independent university system has long been a thorn in the side of the Macri government, which is why the state began to tackle the structural conversion of UniCABA a year ago. There have been massive protests in response—this is about nothing less than the independence of the universities. In June, the recalcitrant lecturers were at the front of the queue when state employees were deprived of their wages for months as a result of empty state treasuries. The closure of the Ministry of Education followed, together with six other ministries, including the Ministries of Culture and Health. There were strikes; the students showed solidarity with the lecturers, but Macri remained hard.
The final legislation passed on Thursday in the city parliament of Buenos Aires, in which Macri’s conservative electoral alliance currently holds a majority. In anticipation, the police had cleared some protest tents on the forecourt and sealed off the street in front of the city parliament with the usual steel barriers on both sides; they also mobilized a massive number of riot police and a water cannon. Clashes erupted, people knocked down barriers, police shot tear gas and attacked the demonstrators with their truncheons. Even the left-wing members of parliament who came out of the meeting on the street were physically harassed. Finally, about 1500 students marched through the city center in a loud demonstration.

The story goes on at some length, dear reader, you may be surprised at how alike the problems of people under oppressive state control are to your own.
