I dunno about opposite, but certainly in opposition on certain points: http://www.un.org/en/universal-declaration-human-rights/inde...
"Article 25.
(1) Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control. (2) Motherhood and childhood are entitled to special care and assistance. All children, whether born in or out of wedlock, shall enjoy the same social protection."
Obviously, this means taking from those who have to give to those who have not, which is pretty strongly opposed by the right-libertarians.
a bunch of the others also conflict with right-libertarian principles; like article 24 limits working hours and says I should get some paid vacation and 26 says elementary education should be free (and compulsory)
