Health cost sharing is a great example of the Catholic social doctrine principles of solidarity and subsidiarity. The principle of solidarity teaches us to help one another directly and to commit ourselves to the common good of all, rather than just living for ourselves. The principle of subsidiarity teaches us to address societal issues at the lowest level possible, closest to those affected. Health cost sharing satisfies both principles because members share and bear the burdens of the medical costs of other members without resorting to depersonalizing bureaucracy. Solidarity simply facilitates the sharing. In addition, members agree to what expenses are shareable in accord with their values, without interference from a federal bureaucracy or an insurance company.
