You'd think CTC would have reduced the numbers per course to help keep the hold pool at a managable size. They're just stitching up those already swimming, who one day hope to get a full time contract, by providing an almost endless supply of cheap cadets who can be hired on temporary flexicrew contracts.
The problem is CTC has expanded so quickly and invested so heavily, that the only way this cost base can be supported is by taking on ~12 wannabes per course, which is blatantly too many. Its an unsustainable business model.
