I worked at a non-semiconductor tenant company in a semiconductor research campus/facility.
Parking lots tell the story. There was a pecking order for the lots, which made it easy to classify. The best off working people were the trades guys. The plumbers and electricians were high-skilled and well paid. Like guys commuting 2,000 miles and buying a second $90k F-250 to drive around town in.
The bigshots were Teslas, BMWs, big SUVs. There were a few corvettes and a Ferrari.
The Fab engineers and workers were all driving old Hondas and Hyundais.
One of my good friends from high school was a mechanical engineer at IBM and a master at some super-critical process for mainframes. They moved to a different architecture and his entire team was just nuked from orbit before they even knew what was happening. He was selling real estate for awhile and eventually got back into engineering.
