Fascinating. Ill admit I've never traveled to Europe. What part is easier? My wife (an American citizen) has gone to Canada fairly frequently and clearing the custom is a quick formality. My narrow minded self can only imagine that short of not having a customs at all, it can't get a whole lot easier.
In Europe it's one or two questions (e.g. "how long are you staying?" and "why are you coming here?"). In Canada it's dozens of questions for 5-10 minutes. TBH as an American the same thing happened whenever I came back home to the US so who knows maybe I'm on some kind of list. At least in the US it's stopped now that I have Global Entry.
