Entitled to Know

(Photodisc)

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
jennifer atkinson asked:

“When did we start calling social security, medicare, and medicaid ‘entitlements’?  Seems like they might well be deemed obligations.”

The Oxford English Dictionary does not yet include this sense of the word “entitlement,” but I believe that it originated with or was at least popularized by pioneering legal scholar Charles Reich. Reich used “entitlement” meaning “right to governmental benefits” in his landmark article “Individual Rights and Social Welfare: The Emerging Legal Issues” in the Yale Law Journal in 1965. He had earlier used the corresponding sense of the verb “entitled” in his even more landmark article “The New Property” in the Yale Law Journal in 1964.
Do any readers have any other quotations whose origins they would like me to attempt to trace?
