Earlier this month, President Barack Obama rolled out a new plan to limit the use of offshore tax havens and crack down on corporate abuse of the tax system. These tax havens siphon over $100 billion a year from the government, and have allowed many U.S. banks to duck paying taxes despite receiving massive, taxpayer-funded bailouts. The president's plan is far from perfect, but comes as a welcome acknowledgment of the unfairness embedded in the current tax code.
