Well, many countries don't agree that returning citizens "need to be examined", or at least not all returning citizens need to be asked questions.

In the EU, at least in my experience, returning citizens are NOT asked questions at passport control. After claiming baggage, you then have the choice of the green or red customs channel. If you pick the green, you may be subject to a spot check, although in many entries I have never been selected for a spot check.

This means that if you use one of the automatic border gates e.g. at Heathrow or Schiphol (which you do not need to sign up for in advance), once you are cleared by the gate you do not need to speak to or hand anything to any official.

The only way you can get anything close to that hands off that treatment in the US is by using Global Entry.
