A solution to that prospect is a substantial Exit Tax, but enforcing it would call for implementation of some very aggressive reporting requirements and restrictive banking regulations once net worth exceeds an above average sum. In other words, if one makes use of this Nation's resources to accumulate appreciable wealth and then decides to remove that wealth from the collective bulk of this Nation's economy into that of another nation, one should expect to be appropriately taxed.
Apparently France's control over the accumulated wealth of its citizens is inadequate.
