Not sure about France wealth tax specifically, but the EU has always had a huge problem with taxes being uneven, especially stuff like corporate tax, with smaller countries “stealing” companies from the bigger ones.
This year a minimum of 15% eu-wide was introduced to stop the tax race to the bottom, something similar could and should be applied to a wealth tax.
