That's what I was thinking, although I don't think Google and Facebook are a problem as they can only provide slightly different choices from within a narrow range that people are already interested in. It's the relentess torrent of brainwashing across all media which frames people's opinions and doesn't allow them to think seriously outside of the narrow choices (2 party system, pro/anti [issue]) which ensures that there'll never be change which actually makes a difference (ie the environment, religious crazies controlling nuclear weapons, increasing gulf between rich and poor, companies subverting democracy via lobbying and trade agreements).
