I certainly will not argue your points... the low wage has removed the older experienced mechanics and there is no way to pass the experience to younger mechanics. This is a problem in many trades, even if pay is good.
I have known many great motorcycle mechanics over the years, but most if not all have retired or left the industry because of pay. The vacuum has been filled by people who should not work on anything, let alone a motorcycle. There are still good mechanics out there, but it’s far and few between... as evidence by the horrible work people bring to me and I have to fix. The amount of tires mounted backwards is mind boggling!
