Even prior to that, many of us watched our parents _very unceremoniously_ lose their "job for life" jobs in the 80s and 90s. The illusion of loyalty to an employer and job security went up in smoke with those layoffs, for me personally.
I really enjoy the people I work with, but I never take stability for granted. Ensuring I'm always updating my resume and taking a couple interviews a year is part of my professional ritual. If it were feasible, we'd move elsewhere, but we both have good social networks and roots here -- which is arguably more "expensive" to a working couple in their early thirties than gold.
I am under no illusions about any company I might work for, no matter what size or how much I like the individuals I work with or for.
Sadly, I don't feel like I will ever put my roots down in a place. I'm of the mind that I always have to ready to pack up and move to the new office if means I can keep my job and lifestyle.
