Bjorn Borg, Come Home

Wealth taxes used to be de rigueur in Europe, where there are only a few holdouts. France's is between 0.5% and 1.8% on assets above $1 million. In Spain, it's 0.2% to 2.5% on assets above $223,000.

But rather than transferring wealth, wealth taxes transfer the wealthy. In Sweden, tennis star Björn Borg, ABBA's Björn Ulvaeus and Ikea founder Ingvar Kamprad are among the mega-rich who have fled the country, taking their money with them.
