BECAUSE THIS MONEY came from Texas, the rise of Lyndon Johnson sheds light on the new economic forces that surged out of the Southwest in the middle of the twentieth century, on the immense influence exerted over America's politics, its governmental institutions, its foreign and domestic policies by these forces: the oil and sulphur and gas and defense barons of the Southwest. As the robber barons of the last century looted the nation's earth of its wealth--its coal and coke, its oil and ore, its iron, its forests, the very surface of its earth to provide a footing for the rails of their railroads--and used part of that wealth to ensure that the nation's government would not force them to give more than a pittance of their loot back to the nation's people, so the robber barons of this century have drained the earth of the Southwest of its riches and have used those riches to bend government to their ends.
