Just about every tool brand has their cheap line. Snap-On's Blue Point is just about all imported re-labeled crap. I have Blue Point tools that I've found at Auto Zone for 1/4 the price.
Matco has their Red line of air tools, those are all imported, but owning a few, I've found they seem to be of good quality, but that same Blue Point tool from above can be had on the Matco truck.
Mac has the same stuff too. I saw some MAC vise grips on the truck one time, 4 different ones in a roll pouch for $20. I thought, hmmm seems cheap, sure enough, Made in China (isn't that what Mac stands for, Made Around China?)
Bottom line: You need to be an informed consumer. Just because the products you bought yesterday where quality made in USA pieces, doesn't mean they are the same today.
Case in point. I had to buy some work boots recently. Looked at all the high end brands from Red Wing, Danner, Dr. Martin, down to Carhartt, Wolverine, etc.. Guess what, they are ALL made in China. Yep, even Red Wing and Danner. Docs were always made in England, no more. I was very disappointed because I don't support the Chinese market, but in this case, I had no choice.
