Sad. And, disappointing.
I’m certain that Mac is not particularly happy with their level of service, but scarcity of technical resources may be the issue. Let’s face it, given the choice of career paths of mature young people today "fixing other people’s stuff" may not be the most rewarding financially, or emotionally. As someone put it: "it’s about the Be Do Haves." I "Be" a <fill in the blank>. Does this align with how I want to define my life and career? "Do" -- do I like doing the work? And, "Have" -- am I making the money (and other benefits) I am looking for? Most of us hit 2 out of 3 at best. But it does offer an explanation of why "bench tech" would not offer the esteemed, highly rewarding career of choice for aspiring individuals with upward mobility.
We still work one day per week (semi-retired) trying to keep good audio gear from ending up in the dumpster. I call it my "involuntary not-for-profit organization." But, we stay after it because there is no one within hours of us that does what we do (several months lead wait time) and it’s hard to turn people away with a strong emotional attachment to their gear. If you are planning a road trip to the midwest (Southeast Missouri) we’ll be happy to take a look.
Best of luck.
