Krugman (

When I first began writing a lot about health care, I often found myself taking the pro-single-payer position against people who argued that it was better to work through private insurance companies. I took to arguing that Massachusetts-type plans were, in fact, just imperfect, somewhat inefficient ways of simulating the results of a single-payer system. And if I thought there was any chance of creating Medicare for All any time in the next decade, I’d be pushing for single payer now.
But what actually seems possible — not in the distant future, but tomorrow morning — is the passage of a Massachusetts-type plan for the United States. And now my argument cuts the other way: what we’re getting will, in its overall results, work a lot like a single-payer system. It will be an imperfect, inefficient simulation; but those on the left who decry it as terrible, evil, nothing but a giveaway to the insurance companies are missing the very real good it will do.

Let me say that I get especially, um, annoyed at people who say that the plan isn’t really covering the uninsured, it’s just forcing them to buy insurance. That’s missing not just the community rating aspect <that premiums can’t be based on medical history (which means that coverage becomes available to people with preexisting conditions)>, but even more important, it’s missing the subsidies. And we’re talking about big stuff: between Medicaid expansion and further support for families above the poverty line, we’re looking at around $200 billion a year a decade from now. Yes, a fraction of that will go to insurance industry profits. But the great bulk will go to making health care affordable.
So how anyone can call a plan to spend $200 billion a year on Americans in need a defeat for progressives is a mystery.
I wish there were a public option in there; I wish there were broader access to the exchanges; I wish the subsidies were even bigger. There’s lots of work to be done, work that may eventually culminate in a true, not simulated, single payer system. But even in this form, we’re looking at something that will make America a more just, more secure nation.
