The insurance system does not work in the medical field, it would never work because insurance is for managing risks that are unknown, like a house flooding or your car getting hit in an intersection.
In medical “insurance” it is often dealing with known issues, and the insurance system is just not set up to deal with preventative care, annual check ups, mammograms, blood tests, or pre-existing conditions. It would be like trying to use car insurance to pay for an oil change, which is just as ridiculous as it sounds in your head.
That’s exactly why the term “insurance” should be used when discussing a single payer system, it’s not really insurance, it should be a collective action group that works together with the medical community to find a middle ground where hospitals can still exist and pay wages to their staff, the people can get the medical care they need without getting thrown into poverty for daring to get sick, and the government benefits from having a healthier population as a whole.
Too bad theres way too much money in the short term in keeping this all private, and having a sicker population, so we have decades of insurance company propaganda to work against, and a huge population of people that don’t understand that by doing single payer health care your taxes would go up, but you also wouldn’t be paying out the nose for medical insurance & medical care (because they don’t cover anything). Also think of a world where your health care isn’t beholden to your employment, all the different choices you’d make in your life.
He absolutely still can, his voting bloc is full of low information voters that just want validation for the racist/misogynistic hate they feel
