We live in strange times: hatred has become a national pastime. It doesn't take much to ignite it: three headlines, two talk shows, and a couple of tweets, and suddenly half the country is judging the other half from the comfort of their sofas, with pre-packaged opinions. Curiously, in this race to point fingers, schools are always mentioned. As if the social fracture were the fault of a poorly corrected dictation or a badly presented media project.

High-complexity schools are today the vanguard of our education system. Where dozens of languages, histories, and expectations coexist, the harshest social inequalities and the most transformative opportunities are also concentrated. In these contexts, the Catalan language plays a decisive role: it can become the passport that opens the door to equal opportunities or, if not worked on intensively and rigorously, it can become another factor of inequality.
