there are many times when a Junior developer will do the job. Larger/more complex/higher paying jobs usually require knowledge of multiple layers of the stack. It is really annoying when someone is able to knock out almost all of a project and then "I don't know how to do this..." when it comes to something outside of their scope. I guess that is the difference between a hacker and a hack. A hacker will figure it out and add it to their own knowledge base knowing they have this information stored away for future use.
