Cato's Michael Cannon has examined the budget gimmicks that underpin Congressional Democrats' claims that the cost of implementing government-run healthcare would (only!) be $1 trillion. He finds:

One gimmick makes the new entitlement spending appear smaller by not opening the spigot until late in the official 10-year budget window (2010–2019).  Correcting for that gimmick in the Senate version, Sen. Judd Gregg (R-NH) estimates, “When all this new spending occurs” — i.e., from 2014 through 2023 — “this bill will cost $2.5 trillion over that ten-year period.”

Another gimmick pushes much of the legislation’s costs off the federal budget and onto the private sector by requiring individuals and employers to purchase health insurance.  When the bills force somebody to pay $10,000 to the government, the Congressional Budget Office treats that as a tax.  When the government then hands that $10,000 to private insurers, the CBO counts that as government spending.  But when the bills achieve the exact same outcome by forcing somebody to pay $10,000 directly to a private insurance company, it appears nowhere in the official CBO cost estimates — neither as federal revenues nor federal spending.  That’s a sharp departure from how the CBO treated similar mandates in the Clinton health plan.  And it hides maybe 60 percent of the legislation’s total costs.  When I correct for that gimmick, it brings total costs to roughly $2.5 trillion (i.e., $1 trillion/0.4).

When we correct for both gimmicks, counting both on- and off-budget costs over the first 10 years of implementation, the total cost of ObamaCare reaches — I’m so sorry about this — $6.25 trillion.  That’s not a precise estimate.  It’s just far closer to the truth than President Obama and congressional Democrats want the debate to be.

Poorer care, longer waits, and $6 trillion in extra costs. That's government-run healthcare.
