So, with most of our manufacturing now gone, just what DOES America make? Trouble, mostly. With 4% of the world's population and 18% of the economy, we have 50% of all the lawyers, all looking to make a killing by looting those few industries that still call America home (like Microsoft). Kids don't want to be scientists and engineers; they've seen how little such people are valued in our country. Based on recent history, kids see the "big bucks" are in corporate law, specifically investment banking, leveraged buyouts, greenmail, junk bonds, in short what other countries describe as "trying to make money grow by shaking it side to side".
With America's ability to actually produce products that can compete on the open world market in decline, it's no wonder that the balance of trade is the problem it is. Nobody buys our export products because we just don't make that many any more, and like or not, we have to buy our appliances from the people who make them, which are NOT Americans. (When Ampex invented the VCR, they didn't even bother trying to find an American company to make it, they immediately sold the rights to Japan).
