(p. 298) David L. Birch and his associates at MIT gained a glimpse of this topsy-turvy domain during the late 1970s when they themselves entered the statistical skunkworks of the economy by conducting the most comprehensive and detailed analysis ever performed on the facts of American small business. Using records from a Dun & Bradstreet sample of 5.6 million firms, the Birch team reached the highly publicized conclusion that companies with fewer than 100 employees created 80 percent of the net new jobs in the U.S. economy during the 1970s. Data from the early 1980s confirmed these findings. In launching jobs, the last were manifestly first in U.S. capitalism.
