They forced me to read about Marxism recently. It's actually quite funny how similar they are to libertarians in some ways. Marxists are concerned that the state uses education to indoctrinate children. Yes! They also believe that those in control use the media to regulate what we know. Again there is something in this many countries.
Liberal democracies still often have centrally controlled, state run schools. England has the BBC and we have the SABC. I also want to stop those in power deciding what children are taught and what the masses see on the news. Of course part of the reason I want to stop them is because education and the media have pervasive left wing bias.
Libertarian and communist utopias are pretty similar in some ways. Take a look at this site. It provides details about anarcho-capitalist Patri Friedman pet project. It's kinda crazy, but Marxists should be able to see where he's coming from.
Update: Oh, and marxists note that government has a monopoly on the use of force. Some libertarians also think that's a bad thing.
