The Manhattan Project was the name of the project.. :) ;)
U.S. factory owners and employment agencies had begun recruiting heavily on Puerto Rico.
After 1945, economic changes transformed Puerto Rico's economy from a monocultural plantation economy into a platform for export-production in factories through what was called Operation Bootstrap. By the 1950s a growing unemployment problem left thousands of Puerto Ricans in need of a fresh start on American companies.
