Raising entry level pay isn't the answer. It's raising the pay for non entry level new hires.

The shortage isn't of pilots, it's only of low time pilots who are (and should be) willing to work at very low wages for a year or two until they actually have experience and aren't low time anymore.

The problem is that the seniority system in the airlines (all airlines, even the big ones) requires that all new pilots be treated as if they've never flown an airliner before and paid accordingly.

Get rid of or highly modify the seniority system at regionals and you'll solve the problem.
