At first reading, I think that this would seem to affect only the wealthy French that establish domicile in Switzerland for tax purposes:
Nonetheless, I would encourage a dialogue here on IBS about the implications.
What would happen if all countries tax their citizens abroad to death? How can we grow wealth in society on both macro and micro scales with all of these punitive regulations? How do we discern between “tax expatriates” and bone fide residents of a country that want to and deserve to pay only the taxes in their country of residence on the income and property they have/receive in such country of residence, without undue influence of their country(-ies) of nationality?
