In Chile, more than 100,000 students and professors poured into the streets of the capital Santiago and cities across the country Thursday for the first nationwide student mobilization since conservative billionaire President Sebastián Piñera took office. The students were protesting a recent ruling by Chile’s Constitutional Court, which overturned a law prohibiting for-profit companies from controlling universities. Piñera also served as president between 2010 and 2014, during which time Chile was rocked by massive student protests demanding an overhaul to the education system.
