On Tuesday, Aetna announced it’s canceling its ObamaCare plans in nearly all states. Count on other major insurers to back out soon as well. When open enrollment starts Nov. 1, the public will see they’re going to have few plans to choose from. Worse, they’re going to be paying lots more for health insurance in 2017 and getting less. Across the country, state insurance departments are announcing double-digit premium hikes – as high as 40 percent in some places. Here in New York, MetroPlus, Care Connect and Affinity are hiking premiums over 20 percent. It’s the Not-So-Affordable Care Act. People who earn too much to qualify for a subsidy will be forced to pay as much as a fifth of their income for health insurance. And they’ll get less choice of doctors and hospitals and prescription-drug coverage. Annual enrollment begins eight days before voters go to the polls. Donald Trump is vowing to repeal ObamaCare. Hillary Clinton is doubling down on keeping and expanding it. Democrats are worried ObamaCare sticker shock will have an 11th-hour impact on the election. They should worry. Affordability was a phony claim from Day One. The law requires everyone without coverage to buy the insurance industry’s product or get clobbered with a financial penalty. Most consumers get taxpayer-funded subsidies and see only a fraction of the true cost. And insurers get year-end lump-sum payments from the government to encourage them to under-price their plans. But only through this year. In 2017, after Obama leaves office, that corporate welfare ends – a major reason why premiums will be skyrocketing. It’s an expensive and deceptive scheme – with taxpayers footing the bill – to make the plans look “affordable,” as the law’s title falsely claims. The public isn’t fooled. Twenty-two million were predicted to enroll by 2016, but only half that number did. Young healthy people decided that the Washington-knows-best benefit package, chock-full of features they didn’t need, was a rip-off. Who wants to pay for pediatric dental coverage when you’re 30 and single? Mostly older, sicker people tended to sign up, causing insurers to incur big losses – some $3 billion a year. Democrats are telling the public not to worry about soaring premiums, because they’ll still be getting their subsidies and won’t feel the pain. That’s true for 80 percent of ObamaCare customers. But beleaguered taxpayers will feel the pain. They’re paying for the subsidies, which are already costing 50 percent more per person than predicted when the law was passed. Also feeling the pain big time are ObamaCare customers who earn too much to qualify for a subsidy. Individuals earning more than $47,500 and couples making more than $64,080 will be whacked with the full premium hike. Already, they’re forced to pay as much as 18 percent of after-tax income for their coverage – and it’s about to get worse. Is there a way out of this? In many states, yes. Millions of people are opting to pay the ObamaCare penalty (2.5 percent of adjusted gross income) and then buy bargain insurance. These plans are temporary, not necessarily renewable and limit what you can collect if you’re sick. But they’re cheap. The administration tried to ban them but lost in federal court in July. Now they’re trying another regulation to prevent consumers from buying low-cost insurance. (Unfortunately, New York legislators have already outlawed such choices.) Meanwhile, some ObamaCare advocates are calling for draconian increases in the penalty for not signing up “to compel more people to meet their responsibility.” Ouch. Clinton isn’t commenting on penalties, but when she first proposed universal health care in 1993, she told Congress she’d consider automatically enrolling those who failed to sign up and garnishing their wages if they didn’t pay. Yikes. Defeating Hillary at the polls could still prevent some of the pain. But it’s voters’ last chance.
