Anyone can use 'nice' to start a process at a lower than default priority, but only root can start a process at a higher than default priority. This is, and has been the policy for decades because of system resources. Can you imagine the (lack of) responsiveness of a system if a multi-user system allowed everyone to use the highest possible priority?
