In discussions of business and society, why is there a tendency to focus on large-sized rather than small- or medium sized firms? Have the corporate ethics scandals of the past decade affected small- and medium-sized firms? If so, in what ways have these firms been affected?

In the 2000's the Enron outrage and different organizations have been in the news in light of their moral infringement. These organizations are settled and have exceptional yields on venture.  

Huge companies are focused as their business runs with high benefits, and makes foundations admired to reprimand when they act deceptive. Interestingly with the legislature that isn't looking for benefits yet is accused of acting in the open intrigue. Little or medium estimated firms, have the points of interest to be inconspicuous in dishonest cases on the grounds that their piece of the overall industry is little.  

Henceforth, huge firms are centered instead of little or medium measured firms.
