Hi Dw
Yes there is that grey area about assembly versus percentage of actual manufacturing. How are the Americans accepting Dewalt, watching the programs made in America you notice in the older ones a lot of Porter Cable and now in the newer ones more Dewalt and cordless.
When I worked for contractors in mid 90s, dewalt was the bees knees for cordless stuff. They lost that to milwaukee. PC was highly regarded for lots, especially routers and belt sanders. Both went to mexico, but not together - hard to be sure about when they got together, but PC was made subbrand to dewalt. Last I looked, they still had some of the old pattern tools (like 362 belt sander and 7518 router), but made in mexico. check that - just looked and 362 is discontinued now.
Almost across the board, milwaukee has replaced dewalt for light/medium site tools (battery types), PC, i couldn't even tell you about the brand (at a cabinet factory, we had PC cordless stuff back in the 1990s, but it probably wasn't as good as dewalt - the alignment of PC is a second tier brand to DW made the next PC cordless tool that I got junk - issues like a chuck that couldn't be tightened easily and wouldn't stay tight, subpar batteries).
I stopped hearing complaints about country of origin when the performance of tools made people forget. Milwaukee stuff is so good for mid-use (like cordless impact, etc) that nobody cares if it's made in China. They recognize the time savings with it, and that's it.
As rules changed about labeling, Dewalt stuff bobbed back and forth between "Made in Mexico" to "Made in USA" to "Assembled in USA". Who knows.
Mexico is much the same - labor is $4 there vs. $25 an hour for total cost unskilled. If you ask for good you can get it (the difference between a mexico fender strat and a fender strat from california is very minimal, limited to things like tiny finish issues and what types of finish allowed, but mexico guitars generally same materials and half the cost).
I always assume that any issues are the retailer. Maybe sometimes they're not in good faith, but they're trying to give people what they want or what they think they want, and maximize their margin. Home depot will give investor updates that clue in on things like this ("market is saturated, so strategy is switching to maximizing per-store revenue and profitability").
But we have two parties here - one who knows what they're getting and will use things until they break, and another who is buying and relying on the sales guy to tell them about quality. The former has lost regard to where things are made among relatives on my dad's side (farmers) and some of my mom's side (same, but with some contractors), and price or toughness of the gadget goes more to service.
Complicated discussion. I don't believe it makes sense for us to do things here that we can't do with any kind of benefit, but higher price. Same as I don't believe that I should buy an arch top guitar made in the US duplicarved and perhaps stretching 5 figures (which is really hard for me to take) when I can *contact* a person (a real person, not a brand) in china and get a hand carved guitar for $2k. There is no difference to me between the custom maker in the US who hand carves (except that guy doesn't exist in any reasonable range) and a guy sitting at a bench in China, except I have had bigger problems with custom american makers (before I started making things for myself) and only minor nits with Chinese makers (you learn who does a good job and just go with them, which sounds an awful lot like working with anyone anywhere).
Long way to say, Dewalt doesn't have the same assumption of quality here that they did 20 years ago, same with PC. I'm sure there are individual tools that DW makes that are still highly regarded (corded angle grinders?), but I don't know what they are. My farming relatives are almost feverish when milwaukee introduces a new heavy duty cordless tool, like guys were when I was in college and Nike introduced a new sneaker design.
