Yes corperations are greedy.

I don't think we should just focus on how greedy they are. That is not the root of the problem. Thinking about it is the answer in my opinion, to see the horror at work in our very capitalistic country. I believe that the corporations are very, very powerful. Power does what power does and will continue to do. Fighting against it is very difficult if not impossible because after all it is incredibly powerful. That is unlikely to change. It is our own lives that we can change and it is the evil of the corporations, in our own inner world that needs to be dealt with, so we are no longer so much under it's spell and accept it's conditions,such as "You must subject yourself to lots of advertising, you must make your child a successful adult as soon as possible, you must work at a job you hate, you must watch lame tv, you must always drive a car, preferably a large expensive one, you must hold irrational beliefs that are handed to you." Wipe those illusions away please.
