Single payer is medicare on steroids.... If you think medicare is bad wait until everyone has government health insurance.
Medicare has been good for me....but only because I have a great supplement. I can go to any doc, anywhere I want. I have a $150 per year deductible for my supplement. And it dropped my insurance costs from $800 per month, yes just for me, to around $400 per month. My script insurance is separate.
But that doesn’t mean I want single payer for everyone. Our insurance costs did nothing but go up with Obamacare. Before we went on Medicare we were paying $1400 per month for our private insurance.
