Ah, from your other comments I thought you were an American for some reason. That makes sense. I think the difference is the size of the US. I've traveled a fair bit for work, but never been asked to leave the country. Jobs that do require international travel often explicitly say so in the description and say you must have a passport. As far as freedom to travel, unless you happen to be on the northern or southern border, you can't just hop on a plane and travel out of country on a whim. It's just flat-out not as easy to travel to other countries here as it is in Europe.
