Do Corporations pay their fair share of taxes?

Corporations and the wealthy in the United States pay the vast majority of taxes to support the country. 5% of the people in the United States pay 95% of the taxes collected. I am certainly not one of these 5% but I do recognize that the wealthy in this country support the rest of us as they pay their share and our share of the taxes. They also produce the jobs through business ownership and investments to companies so that they can expand and offer jobs to the rest of us. It takes this type of investments and business ownership to run this country and probably the rest of the countries as well.
