Obamacare has invented a dangerous new way to hide federal spending, including more than $100 billion designed to look like tax cuts.

In defiance of standard United States government accounting practices (and the government’s standard definitions of terms), Obamacare labels its direct outlays to insurance companies “tax credits” (not outlays)—even though they don’t actually cut anyone’s taxes. In this way, Obamacare is masking some $104 billion in federal spending over a decade.

Obamacare has caused health insurance premiums to skyrocket. It has caused millions of Americans who liked their health plans to lose their health plans. It has caused doctor and hospital networks to narrow. Now the Wall Street Journal reports that the Obamacare exchanges in Alabama and Alaska will each have one—that’s right, one—insurer offering plans. We’re moving toward “single insurer” health care.

In short, Obamacare is wrecking the private health insurance market.

The Congressional Budget Office says that the Obamacare subsidies for private insurance will cost $43 billion this year alone. That’s an average of $5,375 per person for those who have been added to the private insurance rolls—or $21,500 per family of four. Meanwhile, the typical 36-year-old (or younger) who makes $36,000 a year (or more) gets $0 under Obamacare.

Before the passage of ObamaCare’s 2,400 pages of coercive mandates and profligate spending, the federal government had already largely wrecked the market for individually purchased insurance, in three interconnected ways.

First, it had effectively established two different health insurance markets—employer-based and individually purchased—by treating them differently in the tax code. Second, it had given an attractive tax break for employer-based insurance while denying it for individually purchased insurance (except for the self-employed). Third, having effectively split the market in two while favoring the employer-based side, it had made it hard for people to move from the employer-based market to the individual market, as it had allowed insurers to treat previously covered conditions as “preexisting.”

A popular conservative alternative, then, would repeal every word of ObamaCare while fixing this longstanding inequity in the tax code.

Donald Trump had a complete meltdown Thursday night when he got locked in this exchange with Marco Rubio over health care. Rubio kept pressing him on what his plan for health care was, and Trump responded by incoherently talking about getting rid of “the lines around the states.” Essentially, Trump wants to increase competition by allowing insurers to sell plans across state lines without regard to the states’s own insurance regulations.

Setting aside the fact that Trump’s understanding of health care policy is woefully inadequate, his one idea on health care isn’t even a good one. Granted, this is an idea a lot of Republicans have floated and, in theory, increased insurance competition is needed and state insurance regulations are often an impediment to this. But in practice, the idea runs into the buzzsaw of federalism.

Jeff Anderson argues that ObamaCare has an incurable preexisting condition: It eats away at the private insurance market on which it relies. That market cannot survive ObamaCare’s hubristic mandates, and ObamaCare cannot survive the collapse of that market. On their present course, both are doomed. The challenge for conservatives is to figure out how, upon the law’s repeal, to rescue private insurance. If conservatives don’t save that market, liberals will—only it will no longer be a market for private insurance, and there will no longer be millions of purchasers, but just one.
