Turboprop pilots or light jets who go to big jets are way better then wannabes, you don't learn piloting in a sim.
This should a normal step where pilots gain experience on smaller aircrafts and then get hired and get trained by the jet airlines when they have sufficient experience.
The system is completely upside down. The "lobby" of jet ppcs will say otherwise, I call it BS and this people are hypocrites, or they dig their heads in the sand.. It is time for a change.
Jet pilots should have a minimum of 1500 hours crew experience in order to be allowed in.
