The Privileges and Immunities Clause forbids inequity or discrimination against people from out of state, but only concerning basic rights. State's own citizens must be allowed to leave their state in order to enjoy privileges and immunities in any other state.
Some examples of this fundamental rights are: protection by the government of the enjoyment of life, the right to go after and obtain security and happiness, the right to possess and purchase property of any kind, the right to sue on courts, among other rights. These rights frequently centre on the economic right to go after sources of income or livelihood. It also focuses on weather the state is validated in the discrimination, and it analyses if there is a considerable reason for the difference in treatment.
