Not everywhere, just everywhere where supply of people wanting to work in a particular industry far outstrips demand. The entertainment industries always had this (music, film, television, computer games) as well as politics (where you have a lot of unpaid interns) and also girls wanting to become flight attendants (Ryanair makes you pay for the training etc.) In industries where skills are in demand, employers have the treat these skills carefully or lose them to someone else. This includes fast growing industries (Linux, web, mobile) and skills that are both hard and really unsexy to obtain.
