 Further, we should not generally think of social rights as simply giving everyone a free supply of the goods they protect. Guarantees of things like food and housing will be intolerably expensive and will undermine productivity if everyone simply receives a free supply. A viable system of social rights will require most people to provide these goods for themselves and their families through work as long as they are given the necessary opportunities, education, and infrastructure. Government-implemented social rights provide guarantees of availability (or “secure access”), but governments should have to supply the requisite goods in only a small fraction of cases. Note that education is often an exception to this since many countries provide free public education irrespective of ability to pay.
