The U.S. economy reigned supreme in the 20th century, becoming the largest most productive, and most competitive in the world; amazing new technologies were invented and commercialised; the workforce became the most educated in the world; and incomes soared while a large middle class emerged and thrived. As the 21st century approached, however, alarms began to sound about the U.S. economy's ability to remain in this pre-eminent position. Incomes stagnated and job growth slowed. Other countries became better educated and our manufacturing sector lost ground to foreign competitors. Observers have expressed concern that the scientific and technological building blocks critical to our economic leadership have been eroding at a time when many other nations are actively laying strong foundations in these same areas. This book provides an overview of the restoration of American innovation which is the key driver of competitiveness, wage and job growth, and long-term economic growth.
