that shit hasn't mattered for decades, dawg Truly. The whole "I'ma work hard here and get me a pro-mo-SHUN" thinking was being called out as a bullshit lie the first time we had a tech bubble. 'boomers were getting all shitty at GenX over the fact that they'd rather bounce from job to job than sit in one shitty place for six years for two titles and a 1.5% cost-of-living increase every other year. The myth of office mobility has been dead since before you were born, son and the fact that it persists in some zombie state where you give it some credo says a lot more about the power of myth than it does about the egalitarian nature of the modern office. Melanie Griffith got Sigourney Weaver's job because Harrison Ford said she should have it, not because of her merits. You're going to work the gig until you've improved your resume and then you're going to bounce. They know it, you know it, Indeed.com knows it. Now? Now you can bounce damn near anywhere. I posted a shitty receptionist gig. I got fifty applications from over a thousand miles away. The sarariman future was dead in '88.
I think you'll find no one to dispute this, least of all me. The bigger problem is the nature of "work" has been so deprecated that face-to-face communication is a productivity suck. The last real "job" I had, I was "key man" on $23m worth of contracts, roughly 60% of the work we did. There were only about 250 people there. I interacted directly with the CEO exactly once, and despite the fact that he lived a 20 minute drive away, was only in the office a couple times a week. That was 2006. face-to-face interaction will always be king, even if you're hopping jobs like hot cakes every two years.
It kinda sucks though (in a first-world-problem kind of way). I've heard from a bunch of ex-colleagues and peers the same thing; if you bounce from place to place in your twenties, you can easily 150-200% your salary in a few years. But I like where I'm now, so all I can do is squeeze another raise out of here.
