Let's translate that accurately...
greed = profit
immoral = cheating
success = survival
MBAs are taught to succeed, by the rules until the rules fail them, then without (hopefully) getting caught. Employees, materials, information, technology, all these are resources to be used to generate profit.
Corporations do not exist for any purpose than to continue their existence, and, usually, derive a profit from their activities, whatever those may be, while continuing their existence. Shell and holding corporations are specialized forms of corporations, generally structured to accomplish specific purposes.
To decry corporations, and those who lead, manage, or support them as exclusively immoral and/or in opposition to the good purposes of society at large is simplistic at best, and generally misguided. You may not like the corporate method of organizing a business venture, but there are limited options. Because the concept of 'corporation' is for me interchangeable with the concept of 'company', which is literally translated into 'group or gathering'. How you succeed in accomplishing things that require more than a few people in some other fashion is something I cannot fathom. Companies/corporations are not new, and neither are their abuses.
But feel free to point out my naivete, and how horrible the world is because of it and whatever you proclaim is evil, and state your case for not being a willing part of it. We all want to live, so we are all caught in the web of society, and make our way either as best we can, with or without regard for the success of others.
