Unchallenged at the latest Republican debate, all candidates said they would repeal the Affordable Care Act. Not asked by the moderators were any questions about new studies that confirm the ACA has significantly increased the number of Americans with insurance coverage, created jobs and reduced the deficit.

When candidates called Obamacare a “job killer,” where are mentions of the more than 300,000 health care jobs the act added in 2014 alone because of millions of new people given health care? Or the increase in health insurance coverage in every state of the union or people living longer?

What are even more seldom mentioned by the critics are the benefits of the ACA to low-income and minority communities, including in New York City. Harlem, which is home to some of Manhattan’s poorest neighborhoods, and countless other communities like it have seen sharp decreases in the uninsured rate since the act’s passage. Approximately 1.2 million more people received Medicaid coverage in New York City this year under the ACA’s expanded Medicaid. The ACA also played a role in the city’s 2014 employment boom. Of the remarkable 105,100 jobs added in the city last year, almost 30,000 were in the health care sector—the largest job gain of any industry.

This year also saw 2.3 million African-American adults gaining health care coverage. There was a 10.3 percent decrease in the uninsured number. Although all racial minority groups saw significant gains, African-Americans reaped the most benefits of the ACA.

Some of this decrease can be attributed to ACA grants to the Teaching Health Center Graduate Medical Education programs, which allows medical students to work directly in communities with little to no access to proper health care. Harlem’s Institute for Family Health, which provides physical and behavioral health care and dental service to low-income Harlem residents, last year received $4.8 million in grants thanks to the ACA. The institute and other clinics in New York City have relied on such grants to extend care to thousands of New Yorkers.

If the ACA were repealed, the loss of tax revenue and economic activity from the public sector jobs it has created would be costly. The Bureau of Labor Statistics estimates that 311,000 jobs were added in the health care sector in 2014. In fact, as manufacturing jobs have moved overseas, health care is America’s biggest source of new jobs because of the millions of new beneficiaries with new or expanded coverage. According to the Congressional Budget Office, by making health care less expensive for hospitals and individuals, the ACA is projected to save more than $200 billion over the next 10 years and $1 trillion over the next 10.

When opponents say, “Costs are going up,” they conveniently neglect that for the decade before Obamacare passed, insurance premiums went up more than 10 percent each year—a whopping 137 percent total. Now they are either down or just 2 to 3 percent higher each year since passage.

Since October 2010, after the ACA’s passage, the United States has enjoyed 60 straight months—five years—of employment growth. This increase represents the country’s longest job-growth streak since World War II. Additionally, 2014 saw the strongest job growth in the United States since 1999.

The ACA’s biggest triumph has been in providing 20 million more Americans with access to health insurance. The Census Bureau found that last year, every state in the United States experienced an increase in the percentage of people with health care coverage.

As a way to bash the president, the ACA will be an inevitable talking point as the Republican primary approaches. It is unlikely that any of the candidates will admit to its proven successes. Sen. Ted Cruz concluded his performance in the Sept. 16 debate by promising to “through regulatory reform, repeal every word” of the ACA. Trump, Christie and others mentioned “repealing” or “replacing” Obamacare. So much for the 20 million people who, now insured, create the record low uninsured rate. Yet it’s not likely that even a President Cruz would have enough “chutzpah” to take away any or better coverage from tens of millions if elected.
