In my brother's defense. He only does that for the first meeting. Plus, you must remember that he goes into situations where a company that was doing well, has a decent product, and an absentee owner. This approach does tear down the politics very quickly. They all point the pettiness and hatred at him. He does get this companies back on track. It is not my approach, but then again, I am never on time when I have to meet with him.
Again, I am pointing out the in certain circumstances being considered callously and remorselessly is not a bad thing.
Both my brother and I do try to find your ineffecture boss and eliminate them.
For my approach, I generally end up with people who are not employable any where else for various reasons, who are very good at what they do. I am willing to work with these people than a passive/aggressive any day.
However, I am only addressing the situation where a company is in trouble and needs to be placed in a positive direction.
That is why I watch FDA Warning letters

Not everyone is cut out to handle situations that need the quick radical change that is tranformed into a lasting positive direction.
