Every coworker (and each person outside your company with similar skills) is a competitor in a global marketplace for various skills. It's just not very useful or helpful to think about it only in that way. Day to day it's much more helpful to think of my coworkers as fellow travelers, wrenching on the same big distributed machine in the cloud, generally just trying to get shit done and be useful. Speaking as someone who works at Meta, I certainly don't plan my life as if I'll always be employed by Meta, always earning this high of a wage. The ride could end at any minute, and I plan accordingly. 10% is an overestimate, of being fired or backstabbed in any given year, fwiw. The people getting laid off in any given cycle tend to be heavily skewed towards newcomers in my experience.
