Famous quotes containing the word services:
“Men will say that in supporting their wives, in furnishing them with houses and food and clothes, they are giving the women as much money as they could ever hope to earn by any other profession. I grant it; but between the independent wage-earner and the one who is given his keep for his services is the difference between the free-born and the chattel.”
—Elizabeth M. Gilmer (1861–1951)
“Civil servants and priests, soldiers and ballet-dancers, schoolmasters and police constables, Greek museums and Gothic steeples, civil list and services list—the common seed within which all these fabulous beings slumber in embryo is taxation.”
—Karl Marx (1818–1883)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
