Not buying something 'Made In China' will not save anything and you'll miss out on a possible good amp. As Mutt said above, Teddy Wong in the factory doesn't care whether you buy the amp he built. He's just feeding his family and keeping alive.
Poor conditions? By who's standard? Does Teddy Wong (the important person in this story) think conditions are poor? He's probably over the moon to be using tools instead of his hands while he earns his daily bread.
Not buying something made in (Enter Country Here) is just daft. You won't feel any better or sleep any better by not owning a Chinese built amp. This kind of thing achieves nothing. Like I would achieve nothing bombing Downing St. Parliament would still continue after the rubble had been swept under the carpet and they gave the country another night to enjoy, in my name.
