I feel like OP has either never worked outside of tech startups/Silicon Valley or never worked pre-2012 (dont wanna assume tho and this is not meant in a disparaging manner)

A lot of these things exists in other industries for awhile. Like lack of trust (you have to be from 8 to 6 in a lot of Wall St firms) and fear of layoffs (everyone who worked during the financial crisis in 07-08 know this all too well). I would say they are the norm, and the things that OP missed was the exception
