Corporations should pay for the public structures that support the national economy and allow their own businesses to prosper. Without a legal and political structure so supportive of commerce and industry, or a national infrastructure for energy development, research, transportation, and communications, or an educated workforce, America would not have the largest economy in the world. That economy allowed American corporations to prosper and our middle class to grow. Businesses that have done well in America should do right by America. It's time for all corporations to step up and contribute to the public systems that ensure we have a free and democratic society in which every American can succeed and thrive.
