What can still change the world (I wonder)

I mean, which factors are still capable to have a real and overall impact in the world of globalisation, consumerism, TV superpower, enduring North-South disparity. Factors that one person may support, to the extent of his possibilities. Training, education. Of course. But this is a long-term and complex process, where an individual contribution risks to get lost. Media, perhaps. Support honest media could make a difference, wherever in the world. And it exists a very simple way of realising it, the subscription. In developing countries as well as in Europe a reliable newspaper represents a robust device to change the situation. Or at least to understand it.
