Pardon the shift in geography, but in the 90s in the US it was called "buy a job", at Flight Safety (training in the left seat as if for a type rating but no type-rating...initiated by Flight Safety and Comair {Airlines}). This allowed a huge number of RJs to be introduced onto Delta mainline routes, because the Delta MEC back then had been asleep at the yoke

(wheel). Promises, promises...are like pie crusts in the business world, made to be broken.
Many novices are now going to Gulfstream to acquire some FO experience on the B-1900. Does the airline pay these new FOs? Much of the time, no! As for the flightcrew, the FOs pay for the hours and the airline

, some of the time, only pays the Captain. That is a much better proposition for the company than being a scab. Think about it: even prostitutes in a 'red light district' are paid-do they pay you, the customer? Lekker slapen.
On a different note, it appears that for years, a very clever British business scheme has brainwashed lots of its novice pilots into buying their jobs, but from a colonial standpoint, what do we know?
