I wonder also about the number of TFWs and the affect on graduates finding jibs. Back in other times, it was more common to hire graduates in my line of work. These days I see a lot more people applying from abroad and getting on as a TFW, as the company can use the excuse that the TFWs have more experience than a graduate and thus can justify being able to hire them.
The companies are sort of justified, but personally IMO they are taking the quick easy route, when in many cases hiring a graduate and helping them grow into the position would be better. Often times the workers from abroad have alleged experience or education that doesn't always live up to the expectations, and even if they live up to expectations, they often have one foot out the door.
