Economic of a superhero universe

Lately, I've been kind of wondering what jobs there would be in the Marvel or DC universes for normal people and what jobs in the real world would be made unnessecary by having superhumans existing in the world. For instance,In a world where Quicksilver or the Flash live do you really need a Post Office? Couldn't either of them do that as a part time job? going off on a bit of a tangent why didn't any of the Flashes or Kid Flashes or for that matter Quicksilver ever start a delivery company. Seriously, how would UPS or FEDex or any other company compete with under 60 seconds or your next deliver is free. For that matter how would people like Richard Dawkins sell any books, would he have to start writing about some other subject? After all how do you write about God not existing if not only God exists but, so does every God from every mythology does,as well. Maybe he would just write books about what assh**es the gods are. Further more with people like Reed Richards or Mr Terrific wondering around the place would you really the power companies or any of the fuel and energy industries? Well, these are just some of the things rattling around in my empty head,lol.

Charles Xavier: wanted for Child endangerment

As we all are prone to do I sometimes wonder about the changes in our laws and society that would take place if our favorite superheroes were real. Today, I find myself thinking about Prof. Xavier and his school of higher learning. In particular, would the Xavier's School for Higher Learning be able to afford the insurance premiums that would come from having the school destroyed on a regular basis. Also, would Charles Xavier face any child endangerment charges after the Juggernaut or Saber tooth or any of the other the x-Men's rogues attacked the school for the umpteenth time or better yet would the school be able to retain accreditation because of all these problems. Another problem would be permission slips would it be a wise idea to send a slip to the children's parents that went something like this:

Dear Parent(s),
Next week we will be taking a field trip to the Shi'ar Empire in order to take this trip we will be living the solar system. If you wish for your child to participate in this excursion please sign below.

Sincerely,
Charles Xavier
Head Master

How many parents do you think would sign a form like this? How many would object?
Well, this are the types of things I wonder about when I'm in class and I should be paying attention to the course work.
