Actually young Europeans are losing faith in the actual implementation where constantly lying politicians suffer zero consequences while the media floods everything with bullshit as a diversion.
This BS article with it's utter misrepresentation of the actual study cited is a perfect example of the latter...
That the point...
In reality nobody loses faith in democracy. They simply criticise the application/implementation (specifically the EU one that isn't very democratic in the first place and the total lack of consequences for lying politicians).
But the decline of democracy has another facet... the deteriation of media quality and information being replaced by attention seeking and framed clickbait bullshit. Which is what brings you this rediculous misinterpretation of the cited study.
Or: reading this article should not tell you that people lose faith in democracy but should make you lose faith in journalistisc standards at the Guardian.
