Yes, the majority of people can and do stay right where they are or they move, including Americans. I have expat friends living in other countries. They're humans. They get to decide where they want to live.
Some, comparatively very few, people want to come here because where they live is insanely dangerous. A very small portion of that group wants to hurt people. Such is life.
