I found the opposite to be true: the key individuals within the company are the ones who break it, not the faceless corporation. In all cases where I found bad environments it was created and exacerbated by middle management taking directions from clueless higher management and implementing in the most distructive interpretations. It is generally accepted that the number 1 reason for people leaving companies to be the direct manager, but the environment in an entire department or area is a bit above, in the middle management (strict definition of mm is debatable, the idea remains).

In my job I deal a lot with low and middle management in lots of companies. Unfortunately I did not find any exception to the general observation that today's low and middle management is a bunch of incompetent impostors with their career as the only concern, occupation and reason in life. That includes technology companies that I cannot name, but known by various acronyms. And I am saying this as a lower level manager myself.
