Your anecdotes are not data.
The evidence is far more than anecdotal. Anyone who is an active tool user could provide more - ask your local mechanic. The experience I describe is almost universal and transcends the term "anecdodal". Here's some bedside reading: 'What’s in a tool? A case for Made in USA': http://hackaday.com/2016/01/18/whats-in-a-tool-a-case-for-ma... Discussion of the same: https://build.slashdot.org/story/16/01/18/213236/whats-…
I think that outside the US, the reputation of US-made good has never been particularly strong. We see US cars, and compare them to Japanese cars and see mostly failings.
So far as Chinese goods go, I have no particular knowledge of wrenches.
However, I'd note that (Chinese made) Apple products are generally of pretty good quality.
I'd also point out that the ZeroHedge article doesn't really make a strong case that quality is decreasing at all. And you realize the Onion is a parody, right?
