With the exception of the US, who taxes its citizens globally, I would assume this would push many people to move abroad to a country without a wealth tax. France is great and all, but I wouldn&#x27;t want to be a tax resident there. If you&#x27;re worth €50m, it&#x27;s just too expensive.<p>Given you already paid capital gains tax (or income tax) when you generated that wealth, there&#x27;s also the double taxation component. Wealth taxes (at least to me) seem like a great way to punish people who are doing well.<p>At the end of the day, we&#x27;re living in a globalised world, where borders matter less and less (at least in the west).
