Final answer:
Presidents Kennedy and Johnson worked to fix domestic problems such as racial equality, immigration policies, and Cold War tensions.
Step-by-step explanation:
Presidents Kennedy and Johnson worked to fix several domestic problems during their time in office. One major issue they addressed was racial equality. They realized that legal segregation and discrimination were harming the country's reputation and its chances of gaining allies. They made efforts to secure civil rights for African Americans, such as supporting legislation and releasing civil rights leader Martin Luther King Jr. who was arrested during a demonstration.
Another problem they worked on was immigration. They sought to reform existing immigration laws, which were based on a quota system targeting immigrants from Eastern Europe and Asia. The Immigration and Naturalization Act of 1965 revised this system and allowed entire immigrant families to move to the United States.
Kennedy and Johnson also focused on Cold War tensions and the Space Race. Kennedy urged Congress to put a man on the moon and invested in space technologies, which had various spin-offs for industries and marked American technological superiority. However, these investments did not address economic inequalities in low-income communities.
