@benjaminlevi As I’m sure you know, that’s what the right in the US is trying to paint single payer as. Of course, as usual, they couldn’t be more wrong. Mostly it’s because they don’t understand the role of insurance, nor do they understand economics.
Insurance is about spreading the risk. The more people you spread the risk over, the less risk there is for each individual. The largest risk pool we could have is every person in the United States. Single Payer puts everyone in the same risk pool, and thus is most cost effective for all of us.
Now you might say we need competition in insurance products, and normally, this would be true. There is a special problem in health care in the US. Health providers are not allowed to turn away sick patients, even if they can’t pay. They do this anyway, but they are tricky about it, and they violate the whole purpose of this law.
Now who pays for uncompensated care? The public is supposed to. Government pays for the health care of poor people, and elderly people and disabled people. Government is also supposed to pay for care when the uncompensated care in a hospital or clinic is higher than for most hospitals.
That pays for part of uncompensated care. The rest is supposed to come by charging private insurers a little more than they otherwise would in order to make up for the losses for unpaid care. This is called cost-shifting. However, if you are clever, you will notice that this means we all (the entire population of the US) pay for all care provided in the US.
This means we should all be in the same risk pool. However, if you allow private insurance, then you are essentially allowing insurance companies to pick out the healthiest people to insure, and forcing the public to pay for the sick people. I.e., we are guaranteeing a profit to private insurers. And what do we get in return? We’re supposed to get a savings, but since we pay for all care, anyway, there is no savings, overall. There is merely cost shifting from poor people to rich people.
This creates enormous inefficiencies, and drives health care costs up higher that they should be. With single payer, we eliminate cost shifting, and gaming the system, and a significant portion of administrative costs. Single-payer helps us all pay less—enough so that we will all see savings if we switch to a single risk pool for the US.
Well, almost everybody. The health insurers will lose out, since they will no longer be guaranteed a profit for selecting the healthiest people to insure. But why do we need them to do that? What benefit does it provide us? We don’t save money. What’s the point?
