It could be a valuable project for a student to go to a library, or to the Internet, and check what Andrew Mellon actually said in his little book Taxation. After which a check of Internal Revenue Service data would enable the student to find out how much tax revenue was collected from people in different income brackets, before and after the highest tax rate was reduced from 73 percent to 24 percent. The lifelong benefits to the student might include a healthy skepticism toward political slogans and a healthy desire to check out the facts before repeating rhetoric on other issues.
