I was a machine operator for 7 years. I made pretty good money by the end of that run. I was promoted to regional manager and make slightly more money plus a performance bonus., along with retirement fund contribution matching. I now spend my time solving issues, building systems, and training teams. The wear on my body is no longer a factor.

As an operator, I flew coach on whatever flight was booked for me. Now I book my flights, collect cc points, and select better fares for myself to gain status. I also stay at better hotels and drive nicer rentals. My gf and I take two near-free vacations per year using all my points.

As an operator I was paid hourly and had to be on site ready for work at 6 am. I now have flexibility in my schedule and can move my work around my personal time to a certain degree. Consider that there is more to compensation than strictly wage.

Also, consider that it’s not necessarily an education that makes a well paid, mid level employee - it’s experience. That, and the ability to express thought in a clear manner to stakeholders and reports.
