That's overly simplistic. In the Apple scenario, it enriches the partners in the other countries (eg Foxconn), many retailers worldwide, and employees and shareholders. The latter might not be American. Many firms are multinational with money flying in all kinds of directions, even friendly governments.

So, what you say is correct in some ways. Some do get more leverage while others jobs are shipped overseas. Who is getting leverage is every party benefiting from these arrangements. Interesting enough, that includes companies in U.S., South Africa, and China.
