Why has there been a growth in "illiberal" or "partly free" democracies in recent years?

The liberal democracy—a state founded on democratic values and which respects individual liberties and the rule of law—has been held by some as a normative goal for political organization in modern times. However, as Fareed Zakaria observed in a 1997 article in Foreign Affairs "Western liberal democracy might prove to be not the final destination on the democratic road, but just one of the many possible exits."
The rise of illiberal and "managed" democracies such as Hungary, Turkey, Venezuela, and others may prove Zakaria's point. Several reasons have been posited for this:

The global financial crisis of 2008 signaled to large sectors of the population the failure of the institutions guarded and promoted by banner-bearers of liberal democracy and empowered them to reject liberal norms, seeking assurances of safety in alternate leadership regimes.


The increased penetration of the internet has helped erode the influence and scope of traditional media, which is a bulwark of liberal democracy. At the same time, its "siloing" effect can insulate people from views other than their own and increase intolerance.


The rise of illiberal democracy can also be a response to liberal non-democracy. Writing in The Guardian, Dutch political scientist Cas Mudde has observed that "Crucial economic and financial powers ... [have been] externalized to independent institutions, like central banks, governed by technocrats and without significant democratic oversight." This externalization, he argues, is democratic in procedural terms only, with liberal politicians acting as a rubber stamp.
