The Daily Fuckup

President Donald Trump spent the first stretch after signing the Republican tax overhaul behaving as if he had landed a clean political victory and little else. In the White House version of events, the bill was a holiday-season triumph that would cut corporate taxes, simplify the individual code, and set off a burst of growth that would eventually wash through wages, investment, and hiring. That was the message Trump wanted Americans to remember: lower taxes, bigger paychecks, and a president who finally delivered a major legislative win. But the law carried a second story line that was much less useful to celebrate. Buried inside the legislation was a repeal of the Affordable Care Act’s individual mandate penalty starting in 2019, a move that health-policy analysts had long warned would weaken insurance markets and, over time, raise premiums for many people who bought coverage on their own.

That made the tax bill more than just a tax bill, even if the administration preferred to describe it that way. Trump signed the measure on December 22, 2017, and by December 26 the White House was still trying to turn the event into a simple economic victory lap. The problem was that the mandate repeal was not some obscure technical change tucked away in the fine print. It was one of the bill’s most consequential non-tax provisions, and it went straight at a central design feature of Obamacare. The individual mandate penalty was meant to encourage healthy people to remain in the insurance pool, helping offset the cost of covering people who use more medical care. Remove that penalty, and the logic changes. Some healthier enrollees are likely to decide the cost of coverage is no longer worth it, leaving insurers with a sicker group of customers on average and creating pressure to raise prices. That is not a partisan flourish so much as the basic math of insurance, and it is why the mandate repeal quickly became one of the law’s most important long-term consequences.

Republicans had a clear political reason for including it. For years they had campaigned against Obamacare and promised to dismantle it, yet they had repeatedly failed to pass a full repeal-and-replace plan. Tying mandate repeal to the tax package gave them a way to claim at least a partial victory over the health law without having to produce a comprehensive alternative. It also helped unify conservatives behind a bill that was already being sold as a pro-growth, pro-business overhaul. But the bargain came with an obvious tradeoff. A large corporate tax cut and a broad rewrite of the tax code were being paired with a policy change that was expected to reduce insurance enrollment. That meant the legislation could be celebrated quickly by businesses and wealthy investors, while the costs in health coverage would appear more slowly and fall on a much broader swath of Americans. Trump’s sales pitch focused on wages, jobs, and confidence, and those were the claims he leaned on most heavily. Yet the same bill also set in motion a weaker insurance market, which made it harder to portray the package as a pure win for ordinary families.

The health-care concerns were not speculative. The mandate was built into the Affordable Care Act to stabilize the risk pool by keeping more healthy people in the market, helping to balance out the expense of covering people with greater medical needs. Budget and policy analysis had already pointed to the likely effect of repeal: fewer people buying coverage, a sicker average pool of enrollees, and pressure on insurers to respond with higher premiums or narrower participation. That is why Democrats and health-policy groups immediately described the mandate repeal as a trap hidden inside the tax bill. The administration could argue, with some confidence, that the law’s tax cuts would encourage growth and perhaps lift incomes over time. But it had a much harder time dismissing the health consequences, because those consequences were not a theory detached from the text of the law. They were a foreseeable result of changing the incentives that support insurance markets. So while Trump was trying to frame the legislation as a Christmas gift to workers, critics saw something else entirely: a major tax windfall for corporations and higher earners wrapped around a provision that could make coverage more expensive and less stable for everyone else.
