Final answer:
Roosevelt emphasized the importance of creating jobs that serve a necessary purpose in public works projects, aiming to provide both immediate relief and long-term economic strengthening.
Step-by-step explanation:
President Franklin D. Roosevelt is referring to his administration's efforts at job creation during the Great Depression through emergency legislation like the Wagner-Peyser Act and the Federal Emergency Relief Act (FERA).
These bills aimed to provide immediate employment to the millions of unemployed, as well as creating long-term employment opportunities that would strengthen the economy.
However, Roosevelt emphasized the importance of ensuring that the public works projects funded by such legislation were not just for the sake of creating jobs, but rather they needed to serve a necessary purpose that benefited the public and contributed to economic recovery.
