I haven't seen any BGs that are made with 'blood' inside them. So I buy what I like, and what I can afford...
If there are some places where BGs are sometimes made better than in other places and they're not priced beyond my means, I'm okay with that... Why not? -I would think most bassists would like to get the best bass for the price they can manage.
But nowadays so many brands and models are farmed out to other cheaper labor places different from where they were originally created, it doesn't make a whole lot of sense to me to limit one's bass opportunities because of 'the blood' of the folks where they were supposedly made.

Up to you. As for my 'blood' comment: culturally, things that are made from the culture where they came from tend to be better. French wine is generally better than other wine - certainly the champagne vs. sparkling wine. I'd much rather attend a baseball game here than in Asia or anywhere else. You'll see better players play better games in better stadiums. You just will. That was the point.
Your mileage or your experience may vary. I've never had a good experience with basses made in East Asia or Mexico. At least some manufacturers like Fender and Sire have the good sense to offer the cheap instruments at a cheap price. Then there's manufacturers like MusicMan and Lakland who want top dollar - in the $1400-1800 range, for the cheap basses. And I've played those, too, and been completely unimpressed. Then I get a G&L in my hands that's only $300-500 more, and is made in CA, and the difference is like night and day.
Suit yourself. Buy what you want. It doesn't affect me. Just know that for only a few bucks more, you get a superior instrument. You don't have to settle for mass produced, inferior instruments.
