I moved from the USA to France and your statement surprised me. Looking around for some data, I'm seeing around 4,600 French nationals who obtained U.S. permanent resident status compared to 13,000 issued to U.S. citizens by France. So about 3x more US -> France and rising.

On a per-capita basis there are far more people who were born in France now living in the USA than vice versa.

Because a significant percentage of people in every country crave authoritarianism and grift?

The fact that vastly more French people speak English than Americans speak French probably has a lot to do with it.
