In the study of migration patterns, scholars often times point to different “push” and “pull” factors that have influenced migration trends over time.
Historically, the free market structure of the United States’ economy, combined with its stable democracy has been a very strong “pull” factor that has enticed millions of families (including my own) to immigrate here from various corners of the earth.
Conversely, dysfunctional governments that have proven unable to serve their people have historically been very strong “push” factors.
