You might enjoy "Gangster Capitalism: The United States and the Global Rise of Organized Crime"[1]. It's full of cheerful stories like this. One favourite deals with how a company doctor working for Union Carbide IIRC became aware that workers were suffering from some form of poison/lung damage. Rather than tell the workers, he told the bosses -- they ended up giving the doctor a promotion and keeping the medical situation under wraps, leading to some deaths etc.
