Barron then noted that to cover the investments made with the Securities Exchange Company, 160 million postal reply coupons would have to be in circulation. However, only about 27,000 actually were in circulation. The United States Post Office stated that postal reply coupons were not being bought in quantity at home or abroad. The gross profit margin in percent on buying and selling each IRC was colossal, but the overhead required to handle the purchase and redemption of these items, which were of extremely low cost and were sold individually, would have exceeded the gross profit. Barron noted that if Ponzi really was doing what he claimed to do, he would effectively be profiting at the expense of a government—either the governments where he bought the coupons or the U.S. government. For this reason, Barron argued that even if Ponzi's operation was legitimate, it was immoral to take advantage of a government in this manner.
