Final answer:
Under President Johnson, Congress aided children in poverty by implementing social welfare programs, increasing educational funding, and providing free healthcare through the Great Society initiatives, including Medicaid, and education acts.
Step-by-step explanation:
During President Lyndon B. Johnson's administration, Congress assisted young children living in poverty primarily through social welfare programs, increased funding for education, and by providing free healthcare. The implementation of the Great Society program included initiatives such as the Economic Opportunity Act of 1964, which created the Job Corps and the Neighborhood Youth Corps to help end poverty. Furthermore, Johnson directed more funding to public education, established vital healthcare programs like Medicare for the elderly, and set higher standards for consumer products.
Particularly for children, the education reform was a cornerstone of aiming to lift Americans out of poverty. The Elementary and Secondary Education Act and the Higher Education Act were crucial in providing financial assistance to schools and college students from low-income families. Moreover, healthcare for the young and low-income individuals was expanded through the creation of Medicaid. Together, these efforts helped decrease the percentage of people living below the poverty line and expanded opportunities for education and healthier lives for children in poverty.
