Edit: note that many countries would fit the description; at least I know the Flemish are complaining their taxes burning up for nothing in Wallonia and Madrid/Barcelona complaining their taxes disappearing for nothing in Andalusia etc, West Germany in East Germany, but I guess every country has this issue at least at some level.
I think you can easily see from the replies to my comment however that this sentiment is widely shared across europe, which is indeed reflective of the fact that our economic malaise and lack of policy to address it is an EU wide phenomenon
If this is a subject that you think is important then make an effort.

Anecdotally there are articles such as https://ec.europa.eu/social/main.jsp?catId=89&furtherNews=ye... claiming that "half of Europeans support higher taxes" although in the breakdown it also counts taxes paid by others, which is of course easier to support as an individual. But I also can't find a source claiming that Europeans are "widely" unhappy with the taxes they paid and what they get in return.
