Paul Ryan is an excellent choice as running mate for Mitt Romney. He understands federal spending and tax policies in enormous detail. He has said that he started reading federal budgets when he was in high school. He’s also read Global Tax Revolution, my book with Dan Mitchell about the implications of globalization and tax competition. He knows that the American economy will not thrive with high tax rates, especially on business income and capital. He shares Mitt Romney’s goal of chopping the corporate tax rate to revive investment and job creation.
