In the EU, no one can hear you scream https://www.economist.com/europe/2021/02/03/how-europe-dodges-responsibility-for-its-vaccine-fiasco
Remember when the vaccine roll out was “a touching moment of unity and a European success story”?
The commission hasn't covered itself in glory. But who put them in charge? The member states. Constitutional innovation in a crisis has drawbacks. https://www.economist.com/europe/2021/02/03/how-europe-dodges-responsibility-for-its-vaccine-fiasco
Von der Leyen got the job due to a lack of objections rather than wide support. And this was deliberate. Ultimately national leaders do not want a powerful, cunning politician to have the top job in the commission. Quite the opposite. https://www.economist.com/europe/2021/02/03/how-europe-dodges-responsibility-for-its-vaccine-fiasco
So what can you do to complain about the current management? Not much. There is no alternative. There is no commission in opposition.
MEPs could kick out the commission, but they're cowardly. The European Parliament has quite a lot of power, but no idea how to use it. (See below) https://www.economist.com/europe/2020/10/22/the-european-parliament-powerful-yet-puny
This lack of legitimate opposition creates a really unhealthy debate. Criticism is left to fringe parties who think the EU will, inevitably, explode. In response, the EU has to clear the lowest possible bar -- survival -- to claim success. https://www.economist.com/europe/2021/02/03/how-europe-dodges-responsibility-for-its-vaccine-fiasco
In short voters end up being gaslit. The buck is passed, blame is shifted and the idea that things could be better is dismissed. https://www.economist.com/europe/2021/02/03/how-europe-dodges-responsibility-for-its-vaccine-fiasco
