The United States spends more on healthcare as a percentage of GDP than other countries like the UK, Spain, and Japan, yet has many uninsured citizens. Around 46 million Americans lack health insurance due to factors like unemployment, lack of employer coverage, or existing illnesses. Hispanics have the highest uninsured rates at around 32%. The Affordable Care Act aimed to expand coverage, reduce costs, and make healthcare more equitable and accessible. However, there is ongoing debate around the appropriate role of government in healthcare and whether reform will reduce costs or freedom of choice as opponents argue it increases spending and control.
