"And fifth, we must use the decade of the 1980's to attack the basic structural weaknesses and problems in our economy through measures to increase productivity, savings, and investment. With these energy and economic policies, we will make America even stronger at home in this decade--just as our foreign and defense policies will make us stronger and safer throughout the world. We will never abandon our struggle for a just and a decent society here at home. That's the heart of America--and it's the source of our ability to inspire other people to defend their own rights abroad. Our material resources, great as they are, are limited. Our problems are too complex for simple slogans or for quick solutions. We cannot solve them without effort and sacrifice. Walter Lippmann once reminded us, "You took the good things for granted. Now you must earn them again. For every right that you cherish, you have a duty which you must fulfill. For every good which you wish to preserve, you will have to sacrifice your comfort and your ease. There is nothing for nothing any longer.""
