It is difficult for some folks to conceptualize. Insurance is simply spreading the risk among many and determining a payment factor which covers those risks. Actuaries have made the same a science. It is not socialism. It is simple math. In a single payer insurance system there is spreading the risk over the largest possible pool......every citizen in the United States. Determining the risk factor and premium per person, and charging each and every citizen a premium. It is a simple insurance pool. Budgets are simple priorities. As a society we determine the budgetary constraints necessary to pay the premium, and how best to collect the same. No freeloaders, and economy of scale savings. Social Security has been a huge American success. Medicare for all will be a huge American success.
Now the politics come into play deciding how revenues will be collected to fund the insurance plan. There is no politics in what we call an insurance pool, that however has been the providence of idiots who somehow want to attach labels of political systems to what is simply a mechanical and scientific actuarial based system of insurance. The politics comes into play when some have to pay more, and others have to pay less. I say forget the politics. Everybody pays a small amount, and raise the remaining revenue with a 3% sales tax and a penny transaction on all stock trades in America. Some will argue that the tax system is unfair, but a sales tax punishes consumption, and the transactional tax is way overdue. These problems are not difficult once the special interest groups and their shills are removed. This is a simple national health insurance pool which will require the costs to be borne by the users......simple insurance concepts, not political smoke and mirrors.
