The grenadaros - Mexico City riot police - attacked and cleared the teachers' encampment in the main square, the Zocalo, yesterday. Teachers were protesting a pro-privatisation and anti-teacher 'reform'. See how the ruling elites learn from one another. There is a generalised turn to repression, from the US, to Turkey, Brazil, Colombia and most spectacularly Egypt. The most familiar figure on TV news is the riot cop, sometimes backed up by the army.'Hegemony' of course is not just ideological. Brute repression is increasingly the mainstay of bourgeois power everywhere.
