[Bloat] [Rpm] [Starlink] [LibreQoS] On FiWi

[rjmcmahon]

My brother and I installed irrigation systems in Texas where it rains a 
lot. No problem with getting business. Digging trenches, laying & gluing 
PVC pipe, installing controller wires, etc is good, respectable work.

I wonder if too many white-collar workers avoided blue-collar work and 
don't understand that blue-collar workers actually are very interested 
in installing fiber (or Actifi) and being part of improving things.
