I've come across a few jobs lately that serve no identifiable purpose other than self-perpetuation. 

I went to the dirty Jersey Shore today.  There was a girl at the entrance to the beach that wouldn't let me enter unless I paid.  Despite my livid objection, I paid.  But when I thought about it, I noticed it was a little strange that I paid $7 in order to gain access to a public beach.  With this $7, I got a fancy little wrist band, and I was later told that I could now use the public bathrooms (other than the ocean ... ha ... everybody does it).  I figure this girl made about $6-7 per hour, and there were probably about 20 of these people working at any given time.  There are probably a few levels of managers above this girl that coordinate who's working what day and where.  And there are probably a few other people who decide how much to charge and the legal ramifications of charging money to use God's green earth.  And let's not forget the cost of those bracelets!  So basically, my money went to furthering the collection of my money.  My money ensured that this girl would be there the next day in order to take somebody else's money.  My money was being taken because without it, the whole system would fail, and it would be a shame to use a natural resource without the exchange of currency. 

(I know there's some Jersey Shore jerk out there who wants to say, "That money goes to paying the lifeguards and buying new pieces of beach combing equipment".  To that I say, "Shut up jerks.  Nobody likes the Jersey Shore.  The only reason we keep going back is because we remember having a good time there once when we were 7.  We're continually hoping to relive that experience, and we're also continually let down by your overcrowded beaches and your archaic toll roads.") #business
