"Mix" cakes vs. scratch cakes

I am writing a paper on why scratch cakes are better than mix cakes for a class. I do not favor making mix cakes but I am sometimes forced to. I dont see any skill in making mix cakes nor do I see any taste in it. My goal in life is to become a Baking and Pastries chef and I love making everything from scratch. Modifying recipes and creating things of my own is always fun but you cant exactly "modify" a mixed cake recipe. I believe that mix cakes are simple and can be made by almost anybody but unless you dont have the time or money for the ingredients called for I think it is always best to make a cake from scratch.
