This explanation of neoliberalism, from the Guardian, is highly recommended reading.
[T]he public sphere – the space where we offer up reasons, and contest the reasons of others – ceases to be a space for deliberation, and becomes a market in clicks, likes and retweets. The internet is personal preference magnified by algorithm; a pseudo-public space that echoes the voice already inside our head. Rather than a space of debate in which we make our way, as a society, toward consensus, now there is a mutual-affirmation apparatus banally referred to as a “marketplace of ideas”. What looks like something public and lucid is only an extension of our own pre-existing opinions, prejudices and beliefs, while the authority of institutions and experts has been displaced by the aggregative logic of big data.
