wyop, good response.
I don't do machine work but I do woodworking.
Most of my tools are Grizzly. When guys gripe I am sending money to China I tell them to check where their American (name) tools were made. As you said, often off the same Chinese or Tawian assembly line.
Chinese made doesn't mean bad quality, BTW.
Not defending it, I would much rather my money go to American companies and workers. But, my first loyalty must be to my pocketbook.
BTW, I don't, and won't buy any foriegn made guns. The only foriegn made gun I own is my Italian, Pedersoli made Brown Bess musket.
