Yeah, I was a field service tech at a machine tool distributor for 15 years. One day about 7 years ago I realized that more of our customers than not were involved in some kind of arms manufacturing. Everything from components to military armaments to places making parts for AR-15s. Didn’t start that way but the business drifted into that market over time.
I decided to move on and it took me all of 5 years to find a position that; a) I was qualified for, b) paid enough that I wouldn’t lose my house and, c) was relatively safe from drifting into the customer base as the last company.
I don’t even have kids and this whole process was absolutely terrifying. I can easily see how someone with a family to support or less stability in their life wouldn’t feel like leaving was a possibility.
