Final answer:
The Affordable Care Act has improved access to healthcare for children through expanded Medicaid eligibility and the creation of health insurance marketplaces.
Step-by-step explanation:
The Affordable Care Act, also known as Obamacare, has had a positive impact on access to healthcare for children. Before the ACA, many children were uninsured or had limited access to healthcare. The ACA expanded Medicaid eligibility and created health insurance marketplaces, allowing more children to access affordable healthcare coverage. Additionally, the ACA included provisions such as the elimination of pre-existing condition exclusions, preventive care coverage, and essential health benefits, which have further improved access to healthcare for children.
