The thing is, it's possible for the equivalent-of-the-Luddites to be right about the impact on their prospects and way of life, and for it still to be the right thing to do in a global sense.
If an economic shift is going to significantly negatively impact the opportunities your children will have, you are on pretty solid ground getting pissed about it, particularly if it is being driven by people who stand to benefit from your losses. It still might be the right thing to do as a matter of, say, national policy. The real differentiation is what do we collectively do for those impacted - as a culture/government do we try an ease the transition, or take a "sucks to be you" stance. Just because something is/was a net benefit doesn't mean it can't also be horrific cf much of the early industrial revolution.
Overall I think the phrase "Luddite" is commonly used these days to characterize someone who is afraid of technology because they don't understand it. More fairly, it would be used to describe people who are afraid of the impact of technology because they do understand it, possible better than most of their contemporaries.
