Single-pilot freight/charter work is the way to go if you want to improve your piloting abilities. Unfortunately, we all suffer to varying degrees from the "I want it now." mentality. All those hours spent making decisions on your own to keep yourself alive will be wasted however, when you strap yourself into an RJ with a Captain who never did anything before more challenging than flying around a traffic pattern in Florida or Arizona, or repeating "right rudder" while warily watching a level two thunderstorm build on the horizon. You'll likely end up frustrated that you took the road less traveled to build skills that you'll likely never use anymore.
Your Captains will appreciate your skills...that's about it.
That's funny about talking on the radio. Don't know how many times I call the tower to report a midfield downwind for runway XX though.
Today's "regionals" are flying into the busiest airspaces in the world. 250 hour pilots are a liability more than an asset in most cases. As a pilot, I can't blame them for accepting the opportunity given them. I wish the system worked differently.
Time will tell if an increase in accidents/incidents will be enough to stop the business practice of destroying a profession to the point where the best and brightest are no longer interested in pursuing the career because they can do better elsewhere.
