Sadly, America had all these large percentages of industrial might and we also allowed ourselves to tap our resources and use / market them as well. Somehwere along the line, someone got the bright idea that killing the Golden Goose was okay as long as it yielded profit "today" and who cares about the future, as long as we got our profits. They sent the work overseas and lied about needing to compete globally (which was backwards - speak for we do not want to pay an American a living wage). Then as a result, they crippled the buying power of many Americans for they had no income left to afford things because all that was left were stupid "service industry" jobs.
Now we are seeing the end result of greed and it is simply that there are no jobs, and there are no industries and as new closures take place, less people with money to buy things or even afford to live, so more jobs are lost and more places of employment close. Unless this nasty spiral is turned around (and there is no reason it can't) we are doomed as a nation. Just too long a history of tearing everything down in the name of progress.
