Maybe the case is that "bad" culture (i.e. culture that is bad for employees but good for employers) can "work" (i.e. make the company money) for a little while. And that's all the time that it needs to work for, if you have short-term goals like creating a virtual monopoly. Then you can relax and reform you image afterwards, which is fine with you because you already have everyone's business anyway, and they're not going to go elsewhere.
