BRISBANE – At an official dinner in Washington, DC, ahead of November’s G-20 Summit in Brisbane, Australia-born media mogul Rupert Murdoch lectured ministers on the dangers of socialism and big government. A fervent opponent of Australia’s carbon price, and a battle-hardened opponent of US President Barack Obama, Murdoch lauded the virtues of austerity and minimal regulation, and railed against the corrosive effects of social safety nets.
