Some fantasy RPGs treat magic as arcane and thus rare, possibly subject to suspicion by the masses. Other games treat magic as somewhat more prevelant but not ubiquitous.
At some point in this trend, magic may become so commonplace as to be considered a commodity.
What published fantasy RPG and/or setting features this level of magic?
One criterion: The magic affects ordinary commonplace people multiple times on a daily basis (i.e. not just adventurers and not just occasionally).
Also: What major socioeconomic characteristics are a direct result of this degree of cultural permeation?
(See Heinlein's novella Magic Incorporated as an example of such.)
