Lat tax, Fair tax, and U.S. federal (current) tax system comparison

This assignment is a literature review, research paper. It compares the flat tax, fair tax, and U.S. federal tax systems. I am stating that the fair tax system would be the best for the U.S. backed up by credible resources. I have a research proposal that I have completed for this assignment. I can submit to you that proposal, as well as numerous research articles I have found for the assignment if needed.
