I just saw 12 Years a Slave. Combined with the above statement I'm reminded of this post quoting David Loy:
"One might argue…that there are good corporations….The same argument can be made for slavery, there were some good slave owners…. This does not refute the fact that slavery was intolerable…. And it is just as intolerable that today....transnational corporations are defective economic institutions due to the basic way they are structured."
