Well, single payer basically means all healthcare is paid for by the state. Theoretically it doesn't have to be universal, just to be paid for entirely by the state, no private insurance shit. It's what they had in the UK before the tories pissed all over the NHS in 2012. Universal healthcare can be single payer, but it doesn't have to be. It can be a mixed system, where everyone has access to healthcare, but maybe it's your employer who has to pay for your insurance (unless you're unemployed in which case the state pays for it and other shit like that) and you have the option to pay for a private insurance etc. So it is similar to Obamacare in some ways, except it's actually universal and doesn't leave like 30 million people uninsured. It's what many European countries have pretty much. The best way to implement universal healthcare is via single payer of course for many reasons.

Spoilers for when America puts in austerity measures to save costs by forbidding healthcare from being administered to misfits.
