If corporations are accepted to be "evil" (and we have lots of examples of mega-corporations that haven't held to "don't be evil"), then simply taxing them and having them continue to be evil doesn't make a lot of sense. Perhaps it would be better to abolish corporate structures and find a new paradigm with greater personal responsibility with small companies more responsive to customers and their customers' values? If people feel responsible for their actions, then they are more likely to "not be evil", instead of being a raindrop in the flood that believes they should just do as they are told. A large part of the US economy is small business, small businesses can live by their values instead of the inexorable pull towards more profit. I'm not saying all small businesses do, but it's more of a personal choice of their values and their customers' values rather than a large tendency to "become evil with more profit and seeking monopolies".
