I agree with this and would like to add that a culture of frequent re-orgs just brings out a different form of the Peter Principle. Instead of regular people getting promoted to their level of incompetence, the organization now optimizes for politicians getting promoted to their level of incompetence. I've seen my current and former employers lose extremely good engineers because they felt they'd been screwed over by bosses who were optimizing their careers to take advantage of the next re-org.
You can't really prevent politics from rearing its ugly head in a large organization, but the best you can do is make sure that you hire extremely competent, honest and straightforward employees and treat them absolutely fairly. One of my bosses had a really great rule for making decisions on new hires. Besides being technically competent, committed and stuff like that, you need to ask yourself whether you'd like to have dinner with this person every single week. If the answer is no, you probably shouldn't be hiring that person.
