On August 11, researchers at the Yale School of Public Health released a study projecting that a single-payer health system would save the United States $1 trillion and 114,000 lives every year. The study has not been peer-reviewed. Its lead author, Alison Galvani, served as an informal unpaid adviser to the authors of the Senate Medicare for All bill. Its own “conservative” scenario still projects $663 billion in annual savings. None of that is the problem. The problem is what the study doesn’t model.

The $1 Trillion Is a Transfer, Not a Windfall

The study identifies five sources of savings: lower pharmaceutical prices, Medicare-level payments to providers, reduced administrative overhead, less fraudulent billing, and fewer avoidable emergency department visits. Read that list again. Three of the five — drug prices, provider payments, administrative overhead — are not efficiencies. They are transfers. The money doesn’t vanish; it moves from the balance sheets of hospitals, drug companies, and insurers to the federal ledger.

That’s a legitimate policy choice. But calling it “savings” is a rhetorical sleight of hand. If the government cut defense procurement by 20 percent, nobody would call the result “savings” without acknowledging that contractors would lay people off, cancel programs, or go under. The Yale study treats provider payment cuts the way a budget spreadsheet treats a line item — as a number that changes without consequences.

The Study Doesn’t Model the Supply Side

Medicare reimburses hospitals at rates well below commercial insurers — often 20 to 30 percent less. The study assumes those Medicare-level rates become the universal standard. That’s a revenue cut of roughly a fifth to a third for every hospital in America, applied overnight.

The study projects 114,000 lives saved by covering the uninsured and underinsured. But those newly covered patients need somewhere to go. They need hospitals that are still open, physicians who are still practicing, rural clinics that haven’t consolidated into a regional system two hours away. The study doesn’t appear to model what happens to the supply of care when you cut the price of care by a fifth.

A chief financial officer at a rural hospital in western Kansas, reviewing the study’s assumptions on a Tuesday afternoon, put it more plainly: “They’re counting my revenue as their savings. I don’t know how to run a hospital on their spreadsheet.”

That’s not a hypothetical. Rural hospitals have been closing for a decade under the current payment mix. The study’s own logic — that Medicare-level rates are the right price for care — implies that the current commercial rates are inflated. Fine. But if commercial rates are inflated, then the hospitals that depend on them are, in some sense, already overvalued. Cutting their revenue doesn’t just reduce waste. It reduces capacity.

The $304 Billion Nobody Wants to Discuss

The study accounts for $304 billion in additional annual spending to meet currently unmet health care needs. That’s the most honest number in the entire analysis. It’s an admission that the current system rations care — that there are roughly 114,000 deaths a year that are, in some sense, already priced in.

But it also complicates the headline. The $1 trillion in “savings” is partially offset by $304 billion in new demand. The net is still substantial — $663 billion in the conservative scenario. But the composition matters. The savings come from paying providers less. The new spending goes to covering more people. You can’t have both without asking whether the providers will still be there.

The study’s defenders will say the model accounts for all of this, that the $663 billion conservative scenario is robust. Maybe. But the study hasn’t been peer-reviewed, and its lead author helped write the bill it validates. That’s not corruption — it’s just what policy research looks like when you’re honest about it. The pretense of neutrality is the actual problem, on both sides.

The real question isn’t whether single-payer saves money. It’s whether we’re willing to pay providers less to cover more people — and whether the providers will still be there when the newly covered show up. The Yale study answers the first question with a confident yes. It doesn’t answer the second at all.
