All users will be restricted to the Global settings or the various PSETSs, no matter what user they are.
However, the Trusted Users setting is a way around all the Global and PSET limitations.
If you add someone to the Full Privilege trusted user, they and all the processes that they launch will have access to everything on the system.
If you add someone to the Safe Privilege trusted user list, they and all they processes that they launch will have access to everything on the system except for the Critical System Protection resources.
