Americans are not better than other people
Let’s assume this dubious assertion is factual. The corresponding fact is that it would destroy an equal (or probably greater) number of foreign jobs. Those foreign jobs are held by human beings. Human being with families. Human beings with needs. Human beings worth every bit as much as a human being lucky enough to be born in the United States. Just because you can’t see these human beings doesn’t mean they don’t exist. Just because you don’t know these human beings doesn’t mean you shouldn’t care about them.
So what should a considerate person do when they make their holiday purchases? My humble suggestion: Buy the products that best match your needs. Because whoever is meeting your needs is actually pretty deserving of your money, even if they don’t speak your language, or look like you. Even if they live far away.
