The Western world isn't a manufacturing-based economy. I don't know precisely when the USA shifted out of that, but I know that for Canada, we stopped being a manufacturing-based economy in the '40s. What that means is that manufacturing ceased to be the biggest employment sector, because the service sector had grown so large. It's continued to grow, and now the knowledge sector is cleaving off from that and being identified as its own thing, and one that's about to take over as the primary sector.
This is all good. Before we were manufacturing-based economies, we were agriculture-based economies. Moving to manufacturing meant that man-hours were spent more effectively, producing more value, and boosting economic growth. The same was true in moving to service sector jobs (which isn't just cashiers and call center people, it's a huge sector, and includes a ton of white-collar work, like paralegals, HR staff, etc). The same is true of the current expansion of knowledge sector jobs.
What we need is effective retraining programs that are accessible to those who need them, and relocation programs to aid those who can't retrain for some reason. Not everyone's going to be able to retrain, but most could, given the right incentives. That'll likely mean the small mining town where everyone's employed by the mine? That town may cease to exist as the population largely retrains and moves away. But that's fine. That's an issue with the main employer of that town shutting down. It's not an economy-wide issue.
