I HOPE THE FOLLOWING IS HELPFUL AS A WAY TO CONSIDER ANOTHER OPTION.
A person with the confidence, physical fitness, sense of responsibility and mental toughness required to be a 121 pilot is well suited to many other profitable opportunities. Related to options outside the cockpit - The FORWARD PATH & details are often not as clear and the financial risk can be murky.
In 1981, Faced with concerns similar to yours - low income flight jobs. But it was what I really wanted to do. But we faced reality and decided to turn my current gig into an entrepreneurial enterprise, work it smart and expand every molecule. Out of the Navy I had been painting & hanging wallpaper in houses and offices, using every spare cent toward that 121 job when reality (a baby) hit.
We built a business adjusting to new opportunities like real estate &'equipment rental, painting roller coasters and power plants that are shut down in winter evolving to complete rehabilitation of industrial infrastructure projects.
we got the kids through college, debt free, married and independent. We are comfortable and expect to leave a trust fund to our heirs. A PA-32R300 & an RV6 in the hanger help me do what I love to do.
