Key details of Sanders's proposed expatriation tax, including the all-important minimum amount of assets an individual would have to own to qualify for the tax and the way such wealth would be calcuated were not immediately available. Nor was Sanders's press office immediately able to comment.
A number of expatriate Americans interviewed stressed that their concern wasn't with Sanders's strategy of going after wealthy individuals, but with his apparent acceptance of the idea that an expatriation tax is ever acceptable, in any form.
"Any exit tax, let alone one as high as the one Sanders proposes, is a breach of fundamental human rights", said Laura Snyder, an American who has spent the past 25 years living abroad, 23 of them in Paris, where she is now, and who is an outspoken campaigner for American expats' rights.
