* In my view Switzerland is not doing fine because it is wealthy, it is doing well as it was historically difficult terrain to conquer (thus no one bothered to invade it in most wars) and because today it is surrounded by wealthy democracies, all of which are part of the EU and economically closely integrated with Switzerland through the EU-Switzerland agreements. If France wanted Geneva 'back' it could do so without much resistance, similar to the Russia-Ukraine and China-Taiwan dynamicy but this doesn't fly with the other EU countries looking on.
* I can't think of any EU bureaucrats who got in the news for corruption or similar, rather it always seems to be the national political caste which are then sent to Brussels as representatives. So the parliamentarians and commissioners, all of which are political appointees or get their post based on national party lists, and the political staff they bring along. See Qatargate - all Italian and Belgian politicians and party staff.
