Human Rights & Civil Rights

Only a few hundred years ago there emerged the ideal of inalienable rights to life, liberty, property, free speech, freedom of conscience and religion, etc. Yet rights now are routinely claimed to include health care, employment, housing, and education; the Universal Declaration of Human Rights even lists paid vacations. Are rights bestowed by government, or do we possess them simply because we are human? Do we have a "right" to all things we need for a full human life—even if it obligates others to provide them?
