This article is part of my posts on the economic system of distributism. This is from practicaldistributism.blogspot.com which you can find here:
Many people assume that only the federal government can afford to adequately assist those in need. This is simply not true. If the taxes to provide this assistance were collected by the state rather than the federal government, then the state could render the assistance. If they were collected by county government rather than the state, then counties could render the assistance. If the principle of subsidiarity were really being applied, then the tax structure would be distributed so that higher levels of government would not need to step in except where the need went beyond the more local governments.
In regard to the supposed inability of health insurers to contain the costs of health care, in what way does this justify implementing a single payer system? It is arguable that the payment structure imposed by those insurers (and the government) have contributed to the overall increase of costs. Insurance companies make money from people paying premiums. Therefore, it is beneficial for them if the costs of even relatively inexpensive health services remain high enough to make the overwhelming majority of people rely on insurance to pay for all health care.
private initiative – in economic matters also – and the failure to recognize its public function, contribute to the undermining of the principle of subsidiarity …”
