Read the excerpt from Roosevelt’s "Four Freedoms" speech. A part of the sacrifice means the payment of more money in taxes. In my Budget Message I shall recommend that a greater portion of this great defense program be paid for from taxation than we are paying today. No person should try, or be allowed, to get rich out of this program; and the principle of tax payments in accordance with ability to pay should be constantly before our eyes to guide our legislation. What purpose does the underlined portion of this excerpt serve in the argument that Americans should agree to pay more taxes to raise money for entering the war?
