Definition: Obamacare, in its English form as "Obamacare insurance," refers to the Affordable Care Act (ACA), a federal law designed to expand access to healthcare coverage for all Americans under the age of 26 who lack health insurance or are otherwise eligible but cannot afford it due to financial constraints. The ACA provides for free and comprehensive coverage of essential health benefits, including medical care, prescription drugs, preventive services, maternity leave, and long-term disability insurance. It also includes a mandate requiring individuals and employers to provide subsidies to help them pay their premiums, with the goal of reducing health-insurance costs and providing better coverage. The ACA has been praised by many for its efforts to expand access to healthcare coverage and improve access to care for all Americans, especially those who are unable to afford it due to financial constraints. It has also faced criticism from some who argue that the law is not a complete solution to universal health insurance, as it only requires individuals and employers to contribute towards their own costs and does not extend universal coverage to millions of uninsured people.
