The fundamental principle that some people seem to miss is that in a human society a cooperative approach tend to be better for all of the members in the long run (even wolves and monkeys know this). Acting in your own most immediate selfish interest harms others in the short term and yourself in the long run.

There's a few major airline pilots that think all RJ pilots should be taken out and shot...that's obviously not practical. What is realistic is encouraging every entry-level pilot to steer clear of the worst of the worst (gojets, mesa, etc). That would force the bottom end to improve a bit or perish. This is actually not a bad thing for you...you might have to flight instruct a few more months to qualify for a better job, but in the long run you will be much happier.

Mesa pilots are having very real problems getting hired by majors, this is a fact that I have witnessed first hand. I know, I know, your uncle's brother's cousin was a mesa guy and he got hired at FEDEX, there's always exceptions...but you're not going to be one unless you know somebody. If you're new at mesa I'm sure your seniority is climbing for the stratosphere at a rate that would peg the VSI on the space shuttle. But if you want to sober up a little, take a look at the seniority list right below where jet captain upgrades are happening. Pick a name, and watch that name's progression over a six month period. You will probably note that he's not moving at all...captains are not leaving unless they turn 60, die, or drop out to do real estate. Even if you are the greatest, best connected major airline candidate there is, how are you going to get the PIC time if none of those captains leave? Are you -8 or 1900? In that case you can get the PIC. Otherwise...

I would strongly suggest applying to other regionals NOW. You will be glad you did in the long run.
