mal-wart isn't a person, it doesn't have rights. stealing is about taking something from someone - can you steal from a forest? when you pick a mushroom, are you stealing it? corporate personhood is an example of what buddhists call 'maya' - mental concepts that take on their own reality, creating attachment and suffering, illusions. our devil is lord mara, the lord of illusions. if corporations were people, we'd have hanged most of them by now. corporate capitalism erases local capitalistic businesses, mom and pops, with a will. it is not your friend.
