The "externalization" of economic costs is, as I said, a form of argumentation like deconstructionism. It is a form of obfuscation and irrelevant to the discussion. The costs of doing business have always been passed onto the consumers. They have because the consumer pays for everything a business does. No [i]income[/], no business. By talking about "externalizing" economic costs you are putting the cart before the horse. It is a way to sound intellectual but is actually being pretentious.

The state can never straighten the crooked timber of humanity.
