Yes but no one claimed advertising was 'driven by a democratic process'. Marxists keep telling people what they want, and of course lying to them, even as the bodies are piling up. At the centenary of Russian Revolution, with 50 million dead, it's hard to believe one can still see hammer and sickles around the place. Yet one can.
That's exactly why the democratic process part is so important. Without the peaceful exercise of power via democracy, all that's left is violence, and nobody in their right mind wants that.
