The economic "rights" asserted by Roosevelt in his second Bill of Rights differ and conflict with the right to life, liberty and the pursuit of happiness. They are claims on the liberty of others. If I have a right to medical care, you must have a corresponding duty to supply it. If I have a right to a decent home, you must have a duty to provide it.I have never accepted the notion of 'positive rights', but this is the best concise refutation I've seen.
My neighbor's claim to positive rights is actually a claim against my liberty: a claim that he wants the State to back with force.
