But it would absolutely be possible to achieve full, universal single payer coverage for all with a lot of smaller steps.
First and most important, I'd pass all-payer rate setting. The biggest problem isn't how we're paying for health care, it's what we're paying for it. Hospital and drug prices have to come down before we can do anything else.
Virtually every developed country in the world has a law like this.
Here's where I start doing things that would be controversial.
I wouldn't be *banning* employer insurance, but this would encourage a lot of companies to stop providing it.
And boom.
Another advantage is that not only does all the politically hard stuff come last, but worst-case, the politically easy stuff can stand on its own.
