The grass isn't always greener. I think the core underlying issue at all of this is social divides within countries. When groups of people become sufficiently antagonistic towards one another, it really enables widespread corruption because people will actively blind themselves (or handwave away) to the wrongs of "their side" and magnify the wrongs of "the other side" with no limits to the hyperbole.
And Europe is most certainly not an exception to this, especially in current times. For instance 65% of EU citizens do not believe that high level corruption is sufficiently pursued. [1] And basically every EU country (outside of Scandiland) has a majority to vast majority who believe that corruption is widespread in their country.
But public perception doesn’t necessarily reflect actual levels of corruption. Having dodgy planning approved is not the same as buying a seat at the head of the government for a quarter billion dollars.
Corruption is always measured by perceptions. There are many reasons for this but when it comes to high level corruption it's especially clear - high level corruption, in most countries, is rarely pursued, let alone prosecuted. And efforts to do such may themselves be driven by corruption. And people's actions, as on all things, will be guided by their perceptions. And so things like corruption's influence on things like starting a business will be driven largely by perceptions.
