Its complicated

Your country is smaller than most states within the United States excepting a handful of the original 13 colonies.

You get in your car and drive for a day in a straight line and you will cross an international boundary. For someone within the EEUU to do the same they'd need to pick a border state and be facing the Canadian or Mexican border. So, with no incentive to "joy-ride" across intl boundaries, fewer folks have the papers necessary for international travel ( even before the current draconian requirements.)

Since there is no land bridge to Europe ( not since the last ice age.) The options for travel become more expensive than RV camping ones way across the plains states. Add the expense, subtract the comparatively lower wages and subtract the smaller vacations of Americans and you have a formula for being isolated and with fewer opportunities.

Now its my turn to ask the equivalent geographic question. Do Western Europeans do a lot of travel to other continents? Africa, Asia, Australia? And when they do, is the use of languages they're familiar with factor in? Or are they as likely to travel to Nepal as to a former colony like Indonesia?
