> European federalism is very popular in Brussels, much less so elsewhere.
Having more democratic EU institution is currently not related to federalism.
You can currently even have fully democratic institutions in a confederation system with limited power. Switzerland was an example of that.
> the current state of things, "aborted half-way", is a consequence of social engineering that failed to take into account
That is the pretty common eurosceptic speech and fortunately does not match the reality.
Most poll in Western Europe confirms an overwhelming majority of pro-EU position[^1]. It is currently even stronger in the younger generation.
The integration of the EU stopped because there is a political interest to keep it in its current state. An half baked monster is much easier to corrupt and control through lobbying and diplomatic negotiation than a democratic institution.
If you want to convince yourself of that, simply have a look on the last 2023 European Energy market reform.
It is a shit show of hidden national interests not even half covered up.
