They're mincing words. If you have HC through your employer, you already have socialized healthcare, not single payer. Single payer by definition suggests there's only one payer.
If you have Medicare on the other hand, you already have single payer, and it's generally accepted that it operates far more efficiently than private insurers - That is, if you're using the payout as a percentage of "Premium" model.
Only one payer of all hospital bills. And again by that logic isn't anyone with an insurance plan participating in socialized health care?
I have a hard time believing that is true of medicare. It's just economically very counterintuitive. An organization that is less sensative to costs is going to be more efficient than an organization that is? I also seem to re-call a statistic that said medicare has more incorrect billings than all private insurance companies combined.
95 cents of every dollar that goes into Medicare goes towards medical costs.
Compare that to the 60 cents of each dollar with private insurance.
Yet another red herring of a non-fact.
