More than 80 percent of the people who have signed up for health plans through state or federal Affordable Care Act exchanges qualify for subsidies to help pay premiums and out-of-pocket medical expenses. But what about all the millions who don't have access to employer-sponsored health insurance but also don't qualify for subsidies? About half of the 12 million Americans buying health insurance on the individual market are subsidy-ineligible, according to the Urban Institute. Are they all fuming and lining up to appear in anti-Obamacare commercials? Chances are not. As veterans of the individual market, many are accustomed to its shocks and uncertainties.
