Open Question: Failing businesses in regards to management?

In order to increase my stock portfolio's value, i have decided to analyze the equity of industries in hopes to find one that is foreseen to fail in the future, and short-sell it. the famed investor steve eisman predicted the collapse of the mortgage and banking industry by finding out that the banks, in selling mortgages, were giving toxic loans, thus reducing cash flow into the company. i wish to find an industry that is failing because of the design flaws in its set up and nature. semi-professional help at least please.
