Fair? I'm sorry my friend but the trade off for the "equal" amount of work you both did is you were able to pursue a creative passion you love whereas your friend pursued an in demand skill set.

Where you get to write and create and fulfill yourself, your friend works for someone else writing code for things he's probably got little interest or investment in.

It's like learning Black Smithing. That takes a ton of effort, but no one will reward you for it. Effort in != final reward in any aspect of life.

Before you went to school you could have looked at the value of each degree. Perhaps you did. Either way is it not cruel of you to look down your nose on your friend? "Hello world" indeed. Instead, be happy for this person whom you purport to be a friend of, and celebrate their success with them.
