Unions aren't perfect, but they're not literally designed to function in a sociopathic manner. Corporations, on the other hand, as legal entities whose sole function and obligation is to pursue profit by maximizing returns and minimizing costs, are.
Corporations are inherently evil.
I'm sorry, but that is ridiculous.
Sci, I know from what you have said that you have a had a hard time, and that you feel unjustly put upon by the world (I have a very similar age, situation, background & education), but I cannot believe you, being as smart as you seem to be, can put forth ridiculous and naive totalising statements like that.
Edit: I just noted your link, and I must say that from the Economic critics in the reception section of The Corporation, that it is not a perfect source to base your opinions on.
