As someone who has both traveled extensively and hosts Airbnb guests from other countries (currently 2 Italians) I couldn’t disagree more. Europeans actually travel less. Often I hear from them, especially when they are here, how their families and friends question their desires to travel. As in, “why would you go to America?” Plus most European countries host passport percentages about the same as the US. Now if you are referring to Germans going to Austria for the weekend, that is hardly traveling.
