The terminology employed here is so muddled as to be detrimental to the discussion.
Government “entitlements” are not rights — so there is no point referring to them as anything other than “entitlements”. The Constitution does not empower the government to create the many entitlements which it has wrongfully created.
And the rights of you and I under natural law are not “negative rights”. They are natural rights. The Constitution does not add to nor detract from those rights — it limits the government’s scope, power and authority and makes a passing reference to those rights which exist absent any reference to the Constitution — and which are indeed inalienable.
If "positive rights" are synonymous with "entitlements" then they are a code word for partial enslavement of others.
