The so-called "shortage" of experienced pilots in the USA is somewhat overstated. It may become more accurate an assertion in the future, but for now, there are very few incentives to join a US airline. Pay, schedule and benefits for first year pilots are a joke. They are obviously not too desperate for new pilots yet. They have more trouble finding ramp agents for similar pay. The guys applying to the majors these days need rich wives willing to support their hobby.
Best,
