"Corporations exist to make profit for shareholders - since shareholders (the generic blob of shareholders represented by Wall Street) are only interested in short term profits and dividends then their prime motivation is money."
There are a couple of classes of shareholders to consider. The Wall Street crowd are certainly only interested in the short term which can be defined as the end of their current bonus period. Those of us who are pensioners and who actually provided the money invested in this are interested in the long term continuation of profits; we are not particularly happy with the antics of the speculating crowd, nor of those company employees who respond to them. Perhaps throwing personal criminal liability on company executives is long overdue and should be extended to other aspects of company conduct.
