I really think I have an answer.  Starbucks would likely love to be able to set up shops in Vatican City.  Why not make a deal with them, allowing Starbucks in, and requiring they hire as baristas, a certain list of citizens, said list to be provided by the pope. Then change canon law to allow the forced retirement of bishops who are the problem children.  Charge those guys rent for their Vatican apartments,  and put them on the barista list...
