It ebbs and it flows - there are times in history you can fondly remember for their plenty and times you can remember for their scarcity.
The only really new trend, IMO, is that in the modern world (I think for the first time ever) working continuously for the same company is a financial trap. The strangest innovation of the current day is that churn is accepted and retaining skilled employees is de-emphasized compared to... hiring new replacement employees with less skill. This incredibly bonkers habit has gained wide enough acceptance that it's sort of the default business state.
A quote from one of the RPGnet moderators, something to the effect of...
"Transhumanism is about how technology will fundamentally reshape how we live, and how we perceive what it means to be human. Cyberpunk is how it won't."
It seems like you would have to go pretty far back to find a time where that would be a genuinely radical message. The 19th century saw the trusts and rail barons. There was also the East India Trading Company and its affect on India.
I haven't read Gibson's work specifically (though I'd like to), but I always got the sense that humanization and dehumanization were the primary themes of cyberpunk and the dystopian world created by corporations was one of the dehumanizing factors. That may not be fair, though.
