But indeed corporations (which are "people") have moved en masse to Ireland. And New Jersey saw a significant exodus towards lower tax states among its richest. It's not empty threats - it's just that the cost of the taxes has to be higher than the cost of moving. For most people, the cost of relocating is higher than the taxes. For the richest people, this wealth tax might just tip the scales. Ted Arison and Eduardo Saverin are the most famous examples I'm aware of - it's mostly because laws were changed after they managed to move without being taxed. Do you think there are no more loopholes? Do you think these are the only cases?
