Regionals are entry level jobs, and all "jet" jobs now. Filled with the least experience, it's one of the safest places to put a no-experience know-nothing new-hire.

Given a choice between someone with a little "jet" experience" and someone who's been slogging out the weather in a low-performance piece of junk at night, single pilot in ice and heavy traffic, I'll take the second guy. Bonus if he was flying something that required some forethought and planning and skill, instead of throwing the thrust levers forward to takeoff, and idle descents.
