Thanks for the reference.  If you read it closely you'll note that the study's authors are the co-founders of PNHP (Physicians for a National Health Program),"a nonprofit organization that advocates for a single-payer health system. Quoting from your article: “We pay the world’s highest health care taxes. But patients are still saddled with unaffordable premiums and deductibles,” said Dr. Steffie Woolhandler. “Meanwhile, billions are squandered on paperwork, and insurers and drug companies pocket huge profits at taxpayer expense.”
 
Dr. David Himmelstein commented: “Our study shows that universal coverage is affordable – without a big tax increase. In fact, we already pay for national health insurance, but we don’t get it. It’s an outrage that the American people pay sky-high health care taxes, but 33 million are still uninsured.”

I think you just advocated a single payer system instead of the current hodgepodge of private pay insurance, single payer, and socialized medicine systems.
