My brother in law works in machining and made more me than I do (like twice as much) as an AP/IA. Although to be fair he has 10 years more experience and works a shift of overtime every week, whereas I have deliberately stayed in low paying jobs because I love general aviation and small towns, and refuse to move 'up' to the higher paying big city/airline gigs. Also, I put more stock in qol than a paycheck, so I'm not one to work overtime unless it's needed by the company. The other difference is that he's worked nights his entire life.
Notice I said he 'made' more than me ... recently his position was transferred to a different plant that he couldn't commute to, and he hated his new position, so he transferred to a different plant, moved, and is now making a little more than half of what I make.
None of this may directly apply to you, but I think the answer to which profession pays more, and which offers better qol, is highly dependent on where you live, and what direction you take in that profession, their are a lot of variables there.
