From Harry S. Truman, the 33rd president of the United States.
This is from his "Annual Message to the Congress on the State of the Union" speech on January 5th, 1949.
A year before this speech, Harry S. Truman issued two executive orders that enabled fair employment practices withing the federal government and equal treatment and opportunity within the military no matter race, religion or original nationality.
This particular speech that you quoted hoped to encourage national health insurance, raising minimum wage, as well as enabling civil rights.
