Don't be surprised, you grew up and out of the love of aviation. You realized there is more to life. I would get my contractor's license and watch what is going on from the sidelines. If this "shortage" is really going to materialize, you will have time to go back to flying, and you will have the contractor experience and license in your back pocket for the inevitable downturn. If you enjoy contracting and are willing to bust your ***, stay w/ it.
