Amidst the severe 2011 Chilean student protests Piñera shuffled his cabinet and removed Joaquín Lavín from the post of minister of education. With respect to the protest, Piñera has defended for-profit activity in education and proposed to legalize it, rejecting the students' demands for the public ownership of educational establishments. During August 2011, Piñera's public approval declined precipitously amidst continuous protests, to the extent that some polls indicated that he was the least popular Chilean leader since Augusto Pinochet. His approval ratings dropped to as low as 22% according to a CERC survey. As such, Piñera's chances of passing sought reforms were seen as remote.
