Answer:
The Affordable Care Act (ACA), also known as Obamacare, was signed into law in 2010 and implemented several significant reforms to the United States healthcare system. The ACA expanded access to healthcare by requiring insurance companies to cover individuals with pre-existing conditions and by providing subsidies to help low-income individuals and families afford insurance. It also implemented several cost-saving measures, such as requiring insurance companies to spend a certain percentage of premiums on medical care and creating incentives for hospitals to reduce readmissions.
The Lilly Ledbetter Fair Pay Act was signed into law in 2009 and amended the Civil Rights Act of 1964 to extend the time period in which an individual can file a claim for pay discrimination based on sex, race, national origin, or religion. The Act was named after Lilly Ledbetter, who sued her employer, Goodyear Tire and Rubber Company, for paying her significantly less than her male colleagues for the same work. The Act makes it easier for individuals to challenge pay discrimination and helps to ensure that all employees are paid fairly for their work.
The Every Student Succeeds Act (ESSA) was signed into law in 2015 and replaced the No Child Left Behind Act (NCLB) as the primary federal law governing education in the United States. The ESSA maintained the NCLB's focus on accountability and high standards, but it also gave states more flexibility in terms of how they implement these standards. The Act also provided additional support for disadvantaged students, including English language learners and students with disabilities, and it placed a greater emphasis on the role of the arts in education.
The Marriage Equality Act, which legalized same-sex marriage in the United States, was signed into law in 2015. The Act amended the Defense of Marriage Act (DOMA), which had defined marriage as a union between one man and one woman, and it granted same-sex couples the same legal rights and protections as opposite-sex couples. The Act was a significant victory for the LGBTQ+ community and helped to ensure that all individuals are treated equally under the law.
