In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
What caused a need for more regulation?

The US reacted to the Luna program by embarking on the Ranger program in 1959, managed by NASA's Jet Propulsion Laboratory. The Block I Ranger 1 and Ranger 2 suffered Atlas-Agena launch failures in August and November 1961. The 727-pound (330 kg) Block II Ranger 3 launched successfully on January 26, 1962, but missed the Moon. The 730-pound (330 kg) Ranger 4 became the first US spacecraft to reach the Moon, but its solar panels and navigational system failed near the Moon and it impacted the far side without returning any scientific data. Ranger 5 ran out of power and missed the Moon by 725 kilometers (391 nmi) on October 21, 1962. The first successful Ranger mission was the 806-pound (366 kg) Block III Ranger 7 which impacted on July 31, 1964.
What program led to the establishment of the Ranger program?

Developed countries have people with more resources (housing, food, transportation, water and sewage treatment, hospitals, health care, libraries, books, media, schools, the internet, education, etc.) than most of the world's population. One merely needs to see through travel or the media how many people in the undeveloped countries live to sense this. However, one can also use economic data to gain some insight into this. Yet criticism and blame are common among people in the developed countries.
What resources do developed countries have better access to?
housing, food, transportation
