The health-care reform legislation signed into law by President Obama on March 23 marked the biggest attempt to expand access to health care since Medicare and Medicaid were launched in the 1960s. The massive legislation will help 32 million Americans get health insurance coverage and bans insurers from denying coverage to those with preexisting illnesses. It also expands Medicaid to all poor people -- except illegal immigrants -- and gives subsidies to low- and low-middle-income people to buy insurance. But opponents, including every Republican member of Congress, say the coverage expansion is simply too expensive, at a price tag of about $1 trillion over 10 years. They also say new fees and taxes to help pay for the coverage place too big a burden on currently insured people. Meanwhile, a group of state attorneys general is challenging the constitutionality of the law's requirement that everyone buy health insurance.
