Health disparities, or preventable differences in burden of disease, injury and violence, or opportunities ... experienced by socially disadvantaged racial, ethnic, and other populations groups and communities, remain a serious problem in United States (Centers for Disease Control and Prevention, 2008). The grim figures are well known to social workers (NASW, 2009). Compared with white Americans, African Americans have shorter life expectancies and higher rates of disease and death. Although Hispanic Americans, particularly those born in other countries, are in better than nonimmigrant white Americans for at least one generation after immigrating, they lag behind in some measures (Kimbro, Bzostek, Goldman, & Rodriquez, 2008; Russell, 2009; U.S. Department of Health and Human Services [HHS], 2010). Racial and ethnic minorities, including Hispanic Americans, also generally have less access to care than white Americans, and when they get it, it is often inferior (HHS, 2010). Much less is known about disparities from Asian Americans, Arab Americans, and other racial and ethnic groups. During presidential campaign, candidates Obama and Biden pledged to tackle root causes of disparities by addressing differences in access to coverage and promoting prevention and public health (Obama Biden, n.d.). The Obama administration has also pledged to take steps to address disparities (Council on Social Work Education, 2010). Yet, what has been done to date? Thus far, one feat has been enactment of Patient Protection and Affordable Care Act (PPACA) (EL. 111-148) by Congress in March 2010. This article examines potential impact of PPACA on two kinds of disparities: racial and ethnic disparities and class (as determined or influenced by socioeconomic status) disparities. PPACA AND RACIAL AND ETHNIC DISPARITIES A central issue facing many racial and ethnic minorities is lack of access to care. In 2008, 10.8 percent of non-Hispanic white Americans lacked insurance, whereas 19.l percent of African Americans and 30.7 percent of Hispanic Americans no coverage (these figures provide a rough measure of uninsured population at a point in time, not entire year) (U.S. Census Bureau, 2009). If implemented as planned, PPACA ameliorate this problem by providing tax credits and other subsidies to individuals and families earning less than 400 percent of poverty line to assist them in buying coverage through new exchanges (Kaiser Family Foundation, 2010). Because approximately 80 percent of nonelderly blacks, Hispanics, and American Indians and Alaska Natives (compared with 57 percent of white Americans) had incomes below 400 percent of poverty, new law should help reduce disparities in access (Families USA, 2010). The legislation also extend Medicaid coverage to children and adults with incomes below 133 percent of poverty line. PPACA also should decrease group differences in by expanding funding for community centers, which have played a critical role in effort to stem the nation's growing flood of uninsured (Iglehart, 2010, p. 343). Former president George W. Bush described these centers, which grew out of antipoverty efforts of 1960s, as integral part of a care system because they provide care for low-income, for newly arrived, and they take pressure off of our hospital emergency rooms (cited in Iglehart, 2010, p. 343). In 2008, 61 percent of 20 million people served by community were African American or Hispanic American (National Association of Community Health Centers, 2009). The legislation provide $11 billion over five years, an investment that will approximately double number of people seen in centers (Wakefield, 2010). Also, plans be required to offer free preventive and wellness coverage, which many African Americans, Hispanic Americans, and others with high rates of uninsurance often go without (Health Reform for African Americans, n. …
