President Obama took aim at multinational corporations last May at a press conference on international tax policy. I’ll leave out the details here, lest I put you to sleep or explode your brain. Let’s just say that the current system is a mess that drastically needs fundamental reform. Economists describe two contrasting “pure” approaches to taxing the income U.S. companies earn abroad. A “worldwide” approach would apply our domestic tax rules to all income (with a foreign tax credit to protect against double-taxation).
